Kirishima's POV

I've been out of town with my family for an entire week and it's been utter hell. Katsuki was supposed to come with me, but the agency wouldn't let both of us go for a whole week. My immediate family is accepting enough to be fine with me having a boyfriend, but for most of my trip, my grandmother and some bratty cousins were there. I don't understand, they're such jerks. But I'm finally almost home, and I get to see my angel, I'm so happy. I pull into our driveway, and park my car, practically running up to the front door and unlocking it, messing up putting the key in the hole about a jillion times because I'm so excited. As soon as the door swings open I'm greeted by the best, and warmest hug I've ever had. Since Katsuki is shorter than me, his face is buried into my neck, and his arms are wrapped tightly around my waist. With the goofiest grin on my face, I wrap my arms around his smaller waist, and lift him up, as he wraps his legs around my waist.

"Welcome home, Ei," He says, kissing my cheek softly, to which I gently give him a peck on the lips and then we continue to hug.

"Okay, I have to pee so bad, Kat, that was a long drive," I say, with a laugh, which he begrudgingly eventually gets off of me so I can go use the bathroom. He's sitting on the couch, scrolling through something on his phone, probably Twitter, as I come up behind him, "Hey, I'm gonna take my stuff to our room, Kay??"

"Okay, Ei, do you need help?" He asks, looking up from his phone.

"Nope! I got it," I say with a smile as I pick up my suitcase. I have some presents for Kat, and don't want him to see yet, so as soon as it's in my hands I go to our room. After unloading all of my dirty clothes into the hamper, I grab his gifts. Some things for big Kat and some for little. For big Kat, I got him new pentagram gauges for his ears, he's had them gauged for a while and never got anything more than the really basic ones. On top of that, I got him a really nice, orange jacket, if he doesn't like it, I'll take it, I don't care. But for little Kat, I got him a few things, a panda stuffed animals, since little Bakugou has been watching a lot of Ni Hao, Kai Lin. A really nice, fluffy, blanket, that is galaxy styled, with all the zodiac signs on it. And I also got him a rattle to play with, because he's been curious about them. Since he doesn't seem regressed, I wanna take these to the little room we have, and show him when he is, but when I get to the door of the room, it's locked. "Hey Kat???" I shout.
"Yeah???" He shouts back.

"Why is the little room locked?"

He gets off of the couch, and walks over to me, with a slight annoyed look on his face. "I haven't been regressing lately, so I just locked it so we didn't forget next time someone came over. Doesn't seem necessary."

"Have you not regressed this whole time? Baby-"

"And I don't need to! You've had a really tough week and I wanna help yo-" He stops mid sentence, looking at the things in my arms. "Those for me?"

"Yeah!! Of course! I was gonna take them in there for when you regress."

After clearing his throat, he points to our room and says, "Just take them in there for now, the key is all the way in the laundry room."

"Mmmmkay," I say, narrowing my eyes at him, before taking them to our bedroom, setting it on our bed, then go back to the living room.

"So, bubba, i-"

"Hey, Ei, I know you've had a tough week, do you wanna unwind by watching some TV and cuddling?"

"Sure," I sigh, getting behind him to spoon him, before he gives me a weird look.

"What?" I ask, confused.

"You're the one who's had a hard week, you should be getting cuddled."

"But you've had a ha-"

"What do you want to watch?" He interrupts.

"Something calm, turn on a random cartoon, like We Bare Bears," I say, wondering if this will help him realize he can regress. I know he has a lot of trouble wanting to regress in the first place but he's been repressing for a week. He really needs to unwind the tension.

"If that's what you want, now get over here so I can cuddle you."

"But I wanna cuddle you!" I whine, hoping it'll help me get my way. I get my way as always, and cuddle Bakugou while we watch We Bare Bears. "How's my baby doing?" I ask him after an episode.

"M okay," He says softly, noticeable starting to regress, but then he clears his throat and repeats himself, just more maturely and clearly.

"It's okay, baby," I whisper, rubbing his arm gently as he squirms a bit.

"N-no," He whines.

"Baby, you're safe, I'm here, you're safe," I tell him, as I kiss his shoulder a few times, and his head, which makes him giggle.

"But-"

"No cuts no buts no coconuts!" I exclaim, knowing he thinks it's silly when I say that.
"M..can see Panda now?" He asks, referencing the Panda stuffie I brought home with me.

"Of course, baby, wanna come with me to get him?"

"Uh huh!"

Knowing he's a lazy stinky, I pick him up, with his legs wrapped around my waist. Our room is near our living room, so it doesn't take long, and he's able to pick up the panda on his own. Once back in the living room, I sit down, and Kat just stays put in my lap.

"Whatcha wanna name them?" I ask, brushing his hair behind his face.

"Nini," He says happily, looking at him and then hugging me tightly. "Thank you, dada."
