A few days passed after my first day as an intern and right now my second day here almost came to an end. I smiled, remembered how Kacchan's eyes followed my every move during our training, his eyes never once leaving my body. I swear I could see him bite his lip a few times, but he didn't say anything about it.

"Okay, you can go back to the locker room and change. Meet me in my office afterwards" Bakugou stated, ruffing my hair. The other heroes and side-kicks working at this agency were shocked to see Ground Zero treating someone with such care. It wasn't like Katsuki to act so gentle with others and they knew it. Even though Kirishima had jokingly told his colleagues Kacchan has a weak spot for quirkless people, nobody could believe it. To be honest, I wouldn't either if I hadn't known the blonde for basically my whole life.

After I changed into my regular clothes, I went up to Kacchan's office. It was Friday today, meaning I had a whole weekend to work on my research for Todoroki Toya. At first I wanted to change his quirk, but he seems to be resisting against that idea. Something with his father oppressing him, I don't know the details. So now I'm taking a bit of a detour, seeing as I don't want to actually prevent the damage that his quirk causes but more like heal the aftermath.

Something like a smaller, secondary regeneration quirk to heal his burned cells. But I also needed to make sure his body could handle it and the regeneration wasn't too powerful to cause tumors or cancer. It's something I have never done before. A challenge... I kinda like it~!

"You wanted to see me Mr Ground Zero?" I asked as I stepped inside his office, seeing him sit behind his desk, typing on his pc.
"Lock the door" he muttered. I could see a faint blush on his cheeks and giggled as the click of the lock sounded through the room. The curtains of all windows were closed and the only light source came from the led-lighting on the ceiling.

"I noticed you couldn't keep your eyes off me during training~" I grinned, as I walked over to him, seeing him close his laptop to look at me.
"I guess I'm still getting used to the idea of having you back in my life... Nor my brain, nor my heart can seem to comprehend it" he spoke, reaching out for me with a small smile.
"So romantic Kacchan~" I chuckled, sitting down on his lap, getting pulled into a hug immediately. I smiled, relaxing in his hold. This sure felt nice...

"I missed you" he whispered.
"We've been together all day" I mused, practically feeling his eye roll even though I couldn't see it.
"You know what I mean nerd" he muttered, placing a kiss on my cheek as he pulled back a bit.
"If you missed me all that much, why not give me a real kiss hm?" I whispered, slowly leaning in.

I closed the gap rather quickly, pushing his head back a little. He hummed in approval as I nibbled at the bottom lip, asking for entrance. Katsuki gladly opened his mouth for me, letting me dominate the passionate kiss. He was enjoying this just as much as I was. That was until a knock on the door disturbed us.

"Bakubro?"

Ugh, great, it's that idiot... I rolled my eyes, trailing down to Kacchan's neck as he answered.
"What is it hair for brains?!"
The door handle moved, making me glad I had locked the door as I placed small kisses along Bakugou's collarbone. He tilted his head, giving me more room to work with.
"Everything okay dude? Why is your door locked?" Kirishima asked confused.

"Cause I don't wanna be disturbed when doing my fucking job! Now what the hell do you need?!"
"Hmm, I'd like to get a taste of your fucking job~" I whispered in his ear, making his face flush a bright pink. After that I started sucking on his skin in the crook of his neck while Eijirou rambled on about a report on some villain that needed to be handed in today. Katsuki was about to answer but instead let out a small gasp as I bit down on his skin, definitely leaving a mark.

"I-I'll leave it on your desk when I'm done here, don't worry about it!"
"Okay, don't overwork yourself!"
With that he left, making me pull back from Kacchan's previously flawless skin, seeing a nice bruise forming.
"Damnit Deku" the blonde breathed as I licked over the spot, making him bite his bottom lip.
"Don't do shit like that. We're at work" he hissed.
"Correction, you're at work. I'm just here for the fun of it" I smiled, pecking him on the lips.

"Do you want me to leave?"
I could see the struggle in his eyes as I awaited his answer. He let out a long sigh, closing his eyes as he let a hand travel through his spikey hair. He was blushing as he opened them again, not looking directly into my eyes.
"Uhm, I don't know if icyhot needs to give permission first or some bullshit like that but uh could you maybe, I don't know, spend the night with me again?" he asked shyly. It was so cute!

To think that this man is the merciless Ground Zero, a hero who is known to fight without mercy.
"I'll ask Shoto" I giggled, making him give me a small smile as well.
"So you're sending your kids over to Kirishima again?"
"Uhm, I was actually thinking you could have dinner with us o-or something like that? You know, meeting my damn brats and all..." he muttered, letting his hands wander through my hair.

"Oh? Like...a family?" I wondered out loud, leaning onto his chest as I relaxed under his touch.
"I thought it'd be nice... You don't have to agree if you don't want to though"
"No, it's fine. It's just...will they be able to keep their mouth shut about me?" I asked, glancing up at him.
"Hmm, Kota will, but we shouldn't tell Eri who you really are"
"Okay" I whispered, closing my eyes, enjoying this moment of peace.

I'd lie if I said I wasn't nervous. Deku was about to come and have dinner with me and my kids and I wanted everything to go as smoothly as possible. Kota noticed my distressed behaviour, leaning onto the kitchen counter as I prepared the food.
"Don't be so nervous Katsuki, it's just your boyfriend" he stated.
"If anything, I should be nervous. It's not everyday the biggest villain alive comes to visit you"

"Shut up" I grunted, glaring at him. He's damn lucky Eri was watching tv, not hearing a word of what we were saying.
"Izu likes you, otherwise he wouldn't have saved your ass back then... So you've got nothing to be worried about"
"So what is this nervousness about then ? Him meeting Eri? Everyone who lays eyes upon her instantly falls in love, I doubt he won't like her" Kota stated, now starting to set the table.

"I know... I just can't control it, okay?! This evening is important and I want it to be perfect"
The buzzing sound of the bell rang through the air and I froze up.
"Kota, watch the food"
With that I cleaned my hands real quick and went into the hallway. The walk to the front door never felt longer. I took a deep breath before opening the door, giving him a small smile.

"Hi Kacchan! Nice place you've got" Izuku smiled, handing me a bottle of wine.
"Oshi insisted I'd give you this, said that it would be rude to arrive without a gift"
"You can tell that insomniac that you're everything I need Izu... Come on in" I stated, taking the bottle and closing the door behind him. He took off his shoes while looking around, handing me his coat and accompanying me to the rest of the house.

"I'll have to get back to the food now-"
"That's okay Kacchan" Izuku smiled, glancing around.
"You focus on dinner, then I'll watch the children"
"You're barely a few years older" Kota scoffed, a small smirk on his lips.
"Kota! It's been so long!" Deku gasped, hugging the boy. I smiled upon the scene, slowly making my way into the kitchen.

"You've grown so much! I heard from Kacchan that you only wear red shoes now~"
"Dad!" he exclaimed on a whiney tone, glaring at me. I simply chuckled, turning to my food. I heard Izuku laugh and Kota question his appearance.
"Oh, glad you asked! You can call me Suzuki Itsuki, this is my new cover" he grinned.
"Nobody is supposed to know though so ssh"
"That's so cool" Kota gasped, making me smile as I stirred the food around.

The brat was right, I had no reason to be nervous for tonight.
"Oi! Food is ready! Brat, get your sister!" I shouted, putting everything on the table.
"You sound like Mitsuki" Midoriya laughed, making me scoff. Yeah, whatever, so I act like my old hag when it comes to parenting. It's only normal, I guess. Raising my brats the same way I was raised...

"You must be Eri" Izuku smiled as the smaller girl ran in.
"Are you dad's boyfriend?" she asked bluntly, making Kota snort and me groan. Deku chuckled while nodding.
"Yep! My name is Suzuki Itsuki, but you can just call me Itsuki if you like"
"Okay!" she beamed, hopping down on her place at the table. We happily chatted away during our meal and Izuku played games with Eri and Kota while I cleaned everything up in the kitchen.

That was up until Izuku wanted to bring some empty glasses back to the kitchen, tripping and falling, landing into the broken glass. He hissed in pain, trying his best not to curse in front of a small child like Eri.
"Deku!" I yelled, instantly running towards him.
"It's fine... I'm okay" he groaned, hissing as he pulled a shard out of his arm.

"A-are you sure?" I asked in a light panic, quickly handing him some tissues as he removed the pieces from his skin.
"Kacchan, I lived through bullet wounds. This is nothing" he stated, giving me a wide smile.
"I could use a bandage though"
"I-I can help!" Eri offered, trying not to be phased by the blood as she touched Midoriya. Her horn glowed and Izuku's skin fully recovered.

Even more so, his disguise completely vanished. His hair turned a dark green, his eyes regaining their emerald colour and his freckles returning to his face.
"Whoa..." Midoriya gaped, catching his reflexing in the the tv screen.
"I-I... You... Eri, can I ask you what your quirk is?"
The small girl was rather confused by the sudden transformation. I didn't really know how to react to it either.

How was I going to explain this to fucking icyhot? He'll definitely kill me if I expose Deku!
"Eri, time for you to go to sleep" I stated, glancing at Kota.
"I'll put her to bed, come on sis" the younger boy said, grabbing Eri's hand and dragging her down the hall. Izuku frowned, looking at me with his bug puppy eyes.

"What is it Kacchan? You look worried" he pointed out.
"Your appearance..." I breathed, helping him up from the ground.
"Oh, yeah, that's unfortunate indeed... What's Eri's quirk? Can she manipulate someone's DNA somehow?"
"It's called Rewind" I sighed as we sat down on the couch.
"She reversed your body to how you were before you altered yourself"
"Oh really?"

I could see he was instantly deep in thought, muttering all over the place. I didn't understand everything but it was something about Todoroki and the perfect quirk for his research.
"Kacchan, can I take Eri to the union for a day? To study her quirk?" Deku asked, making my heart stop for a second. What..? Take her to the union? To study her quirk..?

Flashbacks of her time with the yakuza passed through my head. How that monster had used her quirk to torture her for years... The experiments, a ruined childhood... It took so long for her to be integrated in the real world, for her to control her quirk, for her to make friends her age... I'll never forget it.

"Her quirk is perfect! With this I'll definitely make a breakthrough in my research-" Izuku happily muttered, only to be interrupted by me.
"No" I growled, clenching my fists.
"Huh? Kacchan, what-?"
"No!" I hissed, now glaring at him.
"I will not let you use my daughter for your experiments! You stay away from her, you hear me?!"

"K-Kacchan..." he whispered in shock, staring at me with big eyes, not knowing what came over me.
"Now if you'll excuse me, I need to give her her goodnight kiss"
With that I left him, stunned on the couch, shocked that I dared speak to him that way. He thinks he knows everything and can get away with whatever he does, but that doesn't fly in my home. Here, I make the rules.
