(TW: angst, blood,violence)
( Kirishima is 20 in this he is a pro hero, Y/N is also 20)

Y/N was a smart girl usually but tonight she thought she must had to be dumb. Tonight was just supposed to be a simple mission with the boys you know just the usual stuff. Like threaten the mafia gang around the block if they didn't stop coming on your territory things were going to get ugly. You were just walking back to your home base with the group you did the mission with when you suddenly got a call from your second in command Mori. "Y/N the heroes are after the gang" he said Y/N looked surprised yes they did criminal stuff but nothing to ever catch the heroes attention. " What happened, why are they after us?" you asked "remember the small group you sent to the bank" yes you recalled it was supposed to be just a simple robbery but you guessed it wasn't. "I remember what happened to them, are they alright" just because you were a mafia leader doesn't mean you don't care for your members you all were like family. "They are alright except for one who got caught" Mori said " well where are they at now Mori" you said, beginning to get angry those heroes better not harm them or I swear you thought to yourself. "They're locked up in a local jail about three blocks from your location" he replied "thank you Mori" you said before you hung up you turned around to your group and said "change of plans boys were going on a rescue mission". You and your group arrived at the jail looks simple enough I can just bust in there through the roof and find them you thought to yourself. "Alright I need two of you to go with me for reinforcement, the rest of you will stand guard out here for when we get out," a chorus of "yes boss" echoed from the small group. You and two of your guys climbed onto the roof of the jail and entered through the vents you crawled until you peeked through a vent and saw the cell they were holding one of your members at. You looked around satisfied that you didn't see any heroes around you whispered to your two guys and said "I'm going to go get them out while no heroes are around you two stay up here shoot any hero you see got it". Both of them nodded that you had complete trust in all your members so you dropped out of the vent and onto the ground you looked around and there were still no heroes thank god you thought. You ran over to the cell that held one of your members in it and they looked up " Boss is that you". You put your fingers up to your lips letting them know to be quiet and went to go look for the keys finding them on a sleeping guard. You began to take the keys of his waist but then he suddenly woke up. He started to yell but then you took out your silencer gun and shot him twice in the chest. Sorry pal but better you than me you thought you took the keys and quickly ran over to the cell letting the gang member out " climb up to the vent there will be two other members there to help you get out don't worry I'll be behind you" you whispered to them. They started to climb up the vent when suddenly one of your members shouted "Boss look out" you turned your head and got tackled to the ground by something heavy. Your members started shooting at the thing no it was a person because they were breathing hard and your eyes widened as the bullets had no effects on this person. "Stop wasting your bullets and hurry up and get out of here" you shouted. All three members hesitated not wanting to leave you behind but you shouted one more time "GO" so they took the freed member and crawled through the vents to the roof. You sighed in relief as the person that tackled you looked at you and said " where did they go?" you shook your head because if you were anything you were most definitely not a snitch especially not to your mafia family. The mysterious person sighed and picked you up and threw you over their shoulder and started walking. You couldn't tell where or the direction all you knew was that you were tired you got the wind knocked out of you literally and your adrenaline was wearing down. Slowly your eyes closed and you feel asleep. When you woke you were tied onto a chair and the person that had tackled you was sitting right in front of you. Your eyes widened as you recognized the mysterious person Eijiro Kirishima, your ex from four years ago was now looking at you with so many emotions in his eyes. Hurt,regret,and amazement was in those beautiful crimson red eyes of his you looked down as you felt yourself get mad your hand started shaking violently. How dare he look at me with those eyes not after "Y/N" your thoughts got interrupted when kirishima had said your name you looked at him glaring as you did. He flinched and said "is that really you" he started to breath shakily it looked like he was about to cry. "Yes it's me kirishima now what do you want" you spat out he then broke out in tears and got up and did the unexpected he hugged you crying into your shoulder. You started shaking trying to get him off of all things you did not want to get touched by him "I-i just can't believe it's you I thought you died everyone did" he said. "Well you were wrong I'm very much alive no thanks to you" he flinched again and looked up at you "Y/N i'm sorry I didn't mean to leave you" bullshit you thought. You kicked him with your foot and he got off you slowly you looked at him and said "so you didn't mean to leave me with villains while you saved bakugou" he looked at you regret shown in his eyes he shook his head "Y/N if I could have saved you too I would have I wanted too but we were on limited time and the building was about to blow and" "and so you just grabbed your best friend instead of your girlfriend who needed you" you said hurt and anger laced in your voice. "Y/N i'm sorry" he said you spat at him and said "I don't need your apologies kirishima but since your sorry how about you just let me go and we forget any of us ever saw the other". Kirishima shook his head "I'm not letting you go not like last time I thought I lost you" "yea well luckily for me I survived" you said Kiri looked at you out of curiosity and said "how did you survive they exploded the building there shouldn't have been any survivors".
Flashback to four years ago
(Y/N is 16
Kirishima is 16
Bakugo is 17 )
You were on a mini mission with your boyfriend Kirishima and his friend Bakugou. You three were set to rescue some civilians from a building who were being held as hostages by villians. The plan was to send you inside first since your quirk was made for stealth. Your quirk is invisibility Bakugo and Kirishima would be outside standing guard and waiting since they were more close combat heroes. You snuck inside and started to release the hostages one by one when suddenly you got shot at by a villain with a gun quirk. How he saw through your invisibility you didn't know but your shoulder was starting to hurt real bad. Kiri and Bakugo, having heard the shot, rushed inside and started to beat up the other villains who came out when they heard the shot. You started to free the other captives when a villain appeared with a detonator. It seemed " your too late heroes this place is going to blow in five minutes" Your eyes widened as panic rushed inside you as you tried your best to free the remaining captives. You finally freed all of them but when you were trying to escape yourself one of the leaders grabbed you by your shoulder making you scream. Kirishima rushed to go save you but the leader took out a gun and pointed it at kiri. "Not so fast boy" he said bullets didn't scare kirishima since he could harden. The leader then shot a unaware bakugou in his leg causing him to shout out and fall down the leader laughed as he said to kirishima " you have three minutes before this whole building explodes you have two choices here boy either save the pretty girl here or save the explosive one over there". Kirishima shook his head and said "I'm not going anywhere without either of them" he then rushed to the leader about to punch him when the building started to shake due to the explosion underneath it. "Haha times up boy it's either her or the blonde who's it going to be you better think fast if you want to live" kirishima hesitated as he looked between you and bakugou he was so conflicted on who to choose but time was running out and fast bakugou was the closest one to him so. Your eyes widened in disbelief as you watched kirishima pick up bakugou and run out of the building without even a second glance to you. "Eijiro" you screamed but it was too late the building started to collapse as a big explosion was heard all around. You passed out after that not remembering how you got out or even if you did you woke up in a strange building with the same leader and a bunch of men looking at you. You were about to fight when the leader said " whoa calm down there sweetheart we mean you no harm" "where am I " you asked the leader looked at you and said "your in my mafia base I'm a mafia leader and I saved your life so that means you have to join my mafia as repayment to me". You wanted to protest but then you remembered how kirishima left you to die "alright" you nodded "I'll join". Meanwhile, Kirishima was outside the building crying as he thought about how he had just left you. You learned that the mafia isn't as scary as you thought it would be. Mr. Gray the mafia leader taught you all the basics how to shoot a gun, fighting and martial arts which you knew some from training at UA. Then came a day when Mr. Gray had got sick two weeks after your 19th birthday as he was on his deathbed. That's when he appointed you as the next mafia leader.
Flashback over
As Kirishima listened he started crying again as he thought about what he had done in the past. You just looked at him and said " I don't know what your trying to accomplish here kirishima but if you want me to forgive you forget it's not going happen if you want to throw me in jail go ahead" kirishima looked hurt " I understand I'm not going to try to get you to forgive me and your not going to jail either" he said. "So what are you going to do then I have a busy life Kirishima I can't just stay here forever so you can cry over me and amaze over how I'm alive I have a mafia gang that needs me" you said you missed your gang a lot. I hope they got to their home base okay you thought Kirishima looked surprised. ''You have a mafia gang" he said you rolled your eyes.'' Yes, Kirishima, what was I supposed to do? You left me to die, the mafia leader saved my life. Can you just let me go please" you said. "I will if you answer two questions for me" he said "fine whatever" you said "one can you risk letting another person see you and two do you still love me?". "For the first one depends on who it is and the second one you left me to die Kirishima , what do you think?" you said as you glared at him. "Well it's bakugou and well even though I thought you died and yes I did leave you Y/N i'm sorry for that i-i still love you" he said "I never stopped actually" you looked at him and said "it's fine if its bakugou and even though you feel that way Kirishima well too bad I don't". Kirishima nodded and went out the door looking back one time before he left to go get Bakugou while he was gone. You reached as best as you could to get the knife you had sheathed in your thigh holder but when Kirishima came back he looked amused. "Don't bother Y/N I took your knife and gun before tying you up I remembered where you liked to hide your surprises" he said as you blushed briefly before looking up to see a tall blonde man with red eyes "well well bakugou it's been a long time how are you" you said. Bakugou's eyes widened out of surprise "Y/N how are you alive shitty hair over here said you died" bakugo asked "still with the same old nickname huh I guess some things don't change" you said. "Don't avoid the question Y/N" Bakugo said "or what you'll murder explosion me just like I told Kirishima after the building collapsed the mafia leader saved my life and now I'm in charge of that same mafia" you said. Bakugo looked surprised for a little bit then said "damn didn't know you had it in you Y/N i'm glad you're alive now that idiot over there can stop crying over you" he said looking at Kirishima. "Bakubro" kirishima shouted he was blushing out of embarrassment bakugou smirked and said "I'll leave you two lovebirds alone" he waved as he put his hands in his pockets and left. Kirishima was still blushing as you said "same old bakugou he hasn't changed at all except for being more calmed down" Kiri nodded "yea believe it or not he now has a wife and a kid so he's has really calmed down a lot". "So is what he said true? Do you cry over me or have you" Y/N didn't know why she was asking because she was supposed to be mad at him but something in her was still soft for Kirishima. "Yes everyday I cried over you Y/N believe it or not I still love you I mean that" he said. Against your better judgment you sighed "I believe you" you said Kirishima smiled and went to untie you after he did you got up and stretched. "Could you stay for dinner please" you heard Kirishima ask you sighed and said "fine but don't think we're going back to being a couple or anything I'm still mad at you" "that's fine I just want you to eat something before you go" he said. So you followed him out of the room into the kitchen that was middle sized he turned and asked " so what do you want for dinner we could have alfredo or pizza" you smiled so he still remembers my favorite food you thought "Alfredo is fine" you said. So the two of you fell into a comfortable silence as you helped him make it when it was fixed. Both of you sat down to eat. Now it's just awkward you thought "so there isn't any way I could get you to forgive me" kirishima asked. You thought about it and said "I'll think about it eiji" you said without thinking Kirishima smiled when he realized you used his old nickname you had given him. You blushed a little and got up to do the dishes while you were doing them Kirishima had snuck up behind you and hugged your waist and smelled your hair "I missed you a whole lot" he said you turned and hugged him secretly you had missed him all these years you wanted to see him so badly but another part of you was hurt because he had left you. So you stopped hugging him and said "I've missed you too eiji but I still don't forgive you but a part of me has still loved you all these years" "I thought you didn't love me anymore" he said. You laughed "I lied eiji honestly you're still a little dull" he blushed and said "Hey!!" You laughed and went to go find your knife and gun "what are you looking for" he asked "my weapons I'm going back to home base tonight" you replied. "Are you sure you want to leave tonight you can always stay and wait until morning" Kiri said you sighed and turned around "eiji although I still love you we're from two different worlds now I just can't go back down the hero path and besides I miss my mafia gang there like family to me" you said. "Please stay" kirishima asked looking sad "now that I know your alive I don't want to let you out of my sight again please" "eiji im a big girl if I can handle a mafia I can handle the world but I'll tell you what I'll try to come and visit when I'm not busy that good enough for you" you said. "You promise" he said, holding out his pinky your heart squeezed a little pinky promises were always big in your relationship with kirishima he never broke them and neither did you. "I promise" you said as you linked your pinky with his you both nodded at each other and then you kissed him on his cheek ever so lightly. Then you gathered your stuff and prepared to jump out the window to go home to your mafia "wait" Kiri then grabbed you and kissed you on your lips taking you by surprise after you looked at him and said "I love you eiji see you" as you jumped out the window and started running to home base. Kirishima looked out the window and smiled "I'll be waiting Y/N" he said. You reached home base and all your members were so surprised to see you a huge chorus of "BOSS" was heard all around as they all rushed around you checking to see if you're alright. You laughed and said "I'm fine c'mon let's go inside it's been a day" the member you had rescued looked at you with regret "boss i'm sorry you got captured because of me" they said bending their head down "don't worry about it I'm just happy your okay" you said putting your hands on their shoulders. "Go get some rest all of you" you said everyone headed to bed after a chorus of "goodnight boss" was heard Mori looked at you "Boss are you really alright"he said worriedly. "I'm fine Mori you go get some rest too I'll tell you about it in the morning" as he went to get rest you went and looked out a window and said "soon Kirishima soon". You smiled as you went to get some rest yourself and you kept your promise. You visited Kirishima whenever you could and you both secretly got married and had a family. Both of you were buried next to each other and your daughter was the one to carry on being the mafia leader and a pro hero.

THE END!!
