(Gundham POV)

After everyone has left the restaurant with the the three fiends in the hospital with the despair disease. I then went to my pretend domain then I went into the actual room I was staying at. I then went to the cameras, I was watching everyone on the camera and my gaze fell upon my despair prince Hajime. He doesn't remember us dating back in high school but that wouldn't matter as long he's in my grasp and that he loves me fully via his own records...

He was trying to find someone, to avoid suspicion from the others for the Mono pad for being somewhere that didn't exist on their pad and they couldn't reach, I left it in my pretend lair and I thought of an idea to get my despair prince back in my arms. I now notice that he was trying to find me.

I went into my pretend lair and the doorbell ringed. I asked who was it but I already knew who it was, "U- um it's Hajime, can I- erm.. may I be in granted access to your lair?" He asked though the door, I opened up the door and let him in.

I closed the door, "So what brings you here mortal?" I asked him, "I- um have something to confess before it's too late." He said blushing a bit, "What might that be?" I asked him, "I love you but I know in this killing game you could become an victim." He blurted out, I went over to him and I kissed him on the lips, and he kissed back happily with his arms wrapped around my neck pulling me closer to him.

I wrapped my arms around his torso pushing me closer to him, I have my eyes closed as we continue to kiss, then we heard the door open and then we immediately got off each other "Okayyyyy wasn't expecting that but it's my fault going in unannounced but I thought that there was an murder happening. Welp have fun I guess?" The yakuza fiend said interrupting the moment with my despair prince and leaving, "I assume that you accept my confession." My despair singularity said, "Yes I accept your confession." I said smiling at him.

(Timeskip to where Mikan was about to be executed)

(Still his POV)

Mikan was laughing like a madman, but her face was filled with beautiful despair, "You know Hajime, Gundham would've done the same with you... and Chiaki... I or Sonia would do this for you again..." Mikan said "N- no he wouldn't, he's not like you neither is Sonia..!" My despair singularity said not knowing what she said was correct.

(Timeskip to chapter four)

(Hajime POV)

We were all walking towards the new island that opened up after Mikan trial. I was with my boyfriend Gundham holding his hand, we both looked around the amusement park and then we all went to the roller coaster and got on.

After the ride we got an book about the last killing game and found out that Byakuya was in an another killing game then we got on the Mono train and I passed out onto Gundham's shoulder and him passing out on my head.

We then went exploring our new place after we are going to stay here for a while with no food and water then we are discussing where we're going to sleep at Gundham somehow convince everyone that I would stay with him in his room.

Everyone agreed that I would stay with him then we all went to bed, after we got to the room, we both went on the bed with my head on his chest and with his arms wrapped around my torso pulling me into a tight embrace.

We both fell asleep like that and it was like that for the next few days. Having no food and water was taken a tole on me but Gundham was able to pull through it.

We then heard the body discovered announcement but we couldn't get over there because the door was blocked and the elevator was broken, we were then given bread and milk, after eating the food, Kazuichi started to fix the elevator and the other boys thought that I should go to bed with Gundham, we both got on the bed and fell asleep like that until it was trial time.

(Timeskip to where Gundham was accused as the murder)

(Still his POV)

No..! Gundham's not the culprit...! 'No, he can't be the blackened' I thought as my boyfriend was being accused as the murder by Sonia, "I'm sorry Hajime but the evidence proves the Gundham's the culprit..." She said frowning, "Bu- but wasn't I with him the whole night since it was also my room too?" I argued back trying to defend him, "Yes that would be the case but you're a heavy sleeper you confirmed that already before we got here." She argued back, she's not right.. Gundham would never do that..

I'm not backing down tho, "But how could he got off me without waking me up because even though I'm a heavy sleeper, I would still wake up if he tried to get off me?" I said with a smirk "I can prove it with this." Sonia said as she showed a needle with unknown liquid "Wha- what's that?" I questioned sweating a bit, "It's a needle filled with something that would make you go unconscious. We found it in Gundham and your dorm." She said calmly.

(Timeskip to where Gundham was about to be executed)

(Still his POV)

Monokuma was acting very weird.. "Y'know that I brought back the despair disease." Monokuma said laughing, "And Gundham was the fortunate victim of it." The bear said, "Fuhahahaha..!" I could hear laughter from my right side and everyone turned around to see Gundham laughing. "Gundham has gotten the remembrance disease like Mikan." Monokuma said, I didn't notice Gundham walking towards me and I felt a grab towards my hands.

Gundham squeezed my hands tightly, "Gah-" I yelped out but Gundham was very close to my face, "What Mikan said was true my despair prince, You probably wouldn't remember but we were dating. Wherever I was, you were close behind after High School." He said blushing and drooling a bit, he then kissed me on the lips, with his grip on my hands getting tighter.

I then felt he was pushed off of me, then Fuyuhiko was in front of me in a defensive position "Leave my brother the fuck alone you monster." He said bitterly, Gundham waved to me goodbye "See you again my despair prince." He said while he was dragged off towards his execution. After the execution, I was given his scarf and I took care of his devas of destruction.

The next day I came in tired, "Mor- morning everyone." I said everyone turns towards me "Hey Hajime, how are you holding up?" Fuyhiko asked "Not that great." I replied, Fuyuhiko pulled me into his lap as I was sitting next to him, I fell asleep like that. I didn't notice the glare on Fuyuhiko as I drifted off to sleep, with Fuyuhiko blushing a bit.

(Timeskip to the AU chapter)

(Still his POV)

The body discovery announcement went off and we headed towards Jabberwock park to see Kazuichi there dead. Everyone was panicking because everyone was together, I just felt numb because I was tired of what's happening.

I didn't really investigate that much, but I gather enough evidence for me to at least pass for helping out in the trail, "The culprit could only be you, but you didn't know that you were the culprit." Sonia said pointing at me, "Wai- wait wha- what, I'm the culprit but I didn't know..?" I said looking down "Yes, and I'm sad to see someone who didn't deserve it go." Sonia said crying a bit. "Hey Fuyu, please survive for me." I said to him patting his head.

(Gundham POV)

I was preparing for the execution but unlike the others I had a button that would stop the execution but he would appear dead for everyone but he would actually survive... but I'm sad to say that he does have to endure some pain.. but I would make it up to him after.. I would also be in his execution when I would push the button but everyone would think that it was Monokuma pretending to be me.

(Hajime POV)

I was running away from something but I didn't know what it was. I then felt a pain in my arm, it was a huge cut on my lower arm, it looked pretty deep, I then felt another pain it was in my leg. I now began to limp a bit, my vision was blurry a bit, I thought I saw Gundham but I knew that he was dead.

I couldn't help but think that it was Gundham though, because I still wanted to think that he was alive. I went towards him "Gun... dham...?" I said almost about to pass out due to blood loss, I collapsed into his arms, It feels.... to real. I then felt a pain on my back. It was a gunshot, my vision faded as I slept into unconscious.

(Gundham POV)

I cried onto his chest pretending to be morning in front of the others, but I knew that he was still alive. The camera turned off signaling that the viewing of the 'execution' was over, I carried him to my actual domain and placed him on the bed and bandaged him up, secureding his wounds.

I laid on top of him and I hear his heartbeat slowed down a bit to normal pace. I then start to worry about my despair prince a bit. I hear him wake up after a bit. "Nghh..." He mumbled out, "Wait.. Gundham...?" He slowly said, he buried his face into my shoulder and he started to sob a bit.

I felt his arms wrapped around my torso pulling me closer towards him, I couldn't look him in the eyes as my own tears started to flow out. I felt a small peck on my head, and I looked up to see Hajime giving me a small closed eye smile.

(Hajime POV)

I think I could understand why Gundham was the mastermind behind all of this. I forgive him for what he did to me knowing that he actually does care about me. I gave him a small kiss and we were like that for a while until we both fell asleep like that.

I later woke up to Gundham getting off me "Gundham where are you going?" I asked him "To check over the cameras to see if there would be another murder." He replied "Get Monokuma to check over the cameras, and come back to bed with me," I sleepy replied "Alright my despair prince, I come back to bed." He said getting back on the bed.

I laid on top of his chest with my head buried into his scarf, we quickly fell back asleep with Monokuma watching the cameras. We both woke up to Monokuma saying that the last trial is about to begin in a few days, we both got dressed into new clothes. We were wearing what we usually wear but it's Monokuma themed.

I was also wearing Monokuma clips onto my hair, "Hey Gundham love, may I ask why you started this killing game?" I asked him "Well if you must know, we were dating in high school but everyone bullied you for not having a talent, all that Fuyuhiko, and Hiyoko was lightly teased you, and at least that Peko and I were able to protect you." He replied wrapping his arms around me pulling me closer to him.

Gundham looked down at the ground in angry "I hated how they treated you, you always came to my lair or the other four lair crying or bruised after what they did to you." He said with a small growl, "I figured why not put them in a situation where they can't bring any harm towards you without them being killed." He said reluctantly releasing me from his tight embrace, "The other three are alive, I faked Peko's execution and I faked Mahiru, and Hiyoko's murder, so those three are still alive." He said with a smile "I'm glad that they are alive." I replied

(Timeskip to the big reveal)

(Sonia POV)

Everyone was shocked.. "So Gundham is still alive." Fuyuhiko said "Yes he is, and Gundham is the mastermind behind all of this and the true murder of Kazuichi murder." I said pointing at his portrait, "So he falsely accused my brother Hajime of murder and he executed his own boyfriend, who was Hajime." Fuyuhiko said bitterly, "Yes as sad that it is that's the truth." I said, 'Poor Hajime, he didn't even knows that his own boyfriend did that to him.' I thought bitterly.

Everyone that was alive turned to Monokuma "Come out now Gundham, you've been caught." Kirigiri said "Upupup, such despair, alright alright I'll come out but I just wanna say something." Gundham said though Monokuma but not in his Monokuma voice "Alright but make it quick." Fuyuhiko said "Peko, Mahiru, and Hiyoko are still alive~" He said in a singing voice.

Fuyuhiko was pissed, "Ar- are you shitting us or are you telling me the truth." Fuyuhiko said, a fog appeared and it disappeared as fast it appeared and we saw Gundham was in his usually clothes but it was Monokuma themed, "Hello subjects." He said "...Subjects...?" Fuyuhiko said.

(Hajime POV)

I was still in the mastermind's room, I was still trying to get ready, once I got ready it was time to reveal myself. Gundham set off more smoke appeared and my head was resting on Gundham's chest with him pulling me closer towards him, once the smoke has disappeared, everyone had a surprise look on their face, "Haj- Hajime?" Fuyuhiko said "Yes...?" I said with a small smirk "Why are you there with Gundham, he nearly killed you during your execution." Kirigiri said with a poker face.
