   Kirishima dodges a flying pillow. Only half an hour had passed but things have already escalated. "I just think you should be small!" He argues calmly. Bakugo hunches over, squeezing their stomach. He's been in pain for a while now, but they've been lightly bickering, and it's clear that Katsuki's in a crappy mood. Eijirou thought he'd get used to it during their relationship, but right now, the boy's attitude is getting on his nerves.
    "I'm not fucking regressing. Fuck that!" Bakugo growls. He's gone pale from the pain. Eijirou puts his effort into not rolling his eyes. He knows it's wrong of him, but he feels a little... Left out? He always thought Katsuki would tell him anything, so why didn't he know they're transgender? Yes, Katsuki was nervous, of course, that's why Eijirou hates that he feels this way. Because he never had a right to know; it just sort of felt like he would.

    "What's wrong with being small? Come on, it'll help you feel better." Kiri says, ruffling their hair. "I'll look after everything. You don't have to do a thing, just relax, okay?" Besides his feelings around Katsuki's impromptu coming out, he hasn't forgotten what he saw just the other day. Something about those tissues sprinkled with blood has been drip-feeding Kirishima the worst anxiety. He can't figure it out.
    Katsuki wrinkles their nose, and for a moment their eyes are all hard, and nasty, and Eijirou feels horrible. But then their shoulders sag, and they clench their teeth, another jolt of pain wringing through them.
    "I'm sorry. Fuck... I..." He says, head hanging. He sounds weirdly defeated. He leans against his boyfriend, and when his head tilts up again, Eijirou sees his thumb lingering around his lips. Kirishima's eyes soften, and he pulls him into his chest. He's still not a pro when it comes to this stuff, but he's trying.
     "That's it, good boy." He says, kissing them on the head. Katsuki buries his face into Eijirou's neck.
     "Tummy hurts. Make it better." He mumbles. His voice is changing like it has before. Eijirou brushes a hand through their hair. Maybe he should have given Bakugo some medicine before prompting him to go into littlespace... No kid likes medicine.

    "Aw, I know it hurts, dude." Eijirou sympathises. "But you've been super brave, huh?" Bakugo nods. "Brave little boy." Kirishima smiles slightly as Bakugo's thumb slips into his mouth. Eijirou stands, and hunts for some paracetamol or similar. When he returns to his little one, he finds them chewing the corner of their blanket and rubbing their feet together. It gives Eijirou a warm feeling. He sits down and holds the glass of water to them. Bakugo holds it in both of his hands, watching Kirishima remove a pill from the spread.
     "Mm, no." Katsuki huffs once he's processed what's going on. "Medithin's weird."
  "It doesn't taste of anything. You just swallow it."

   Kirishima gives him a pleading look. "Lovebug, can you swallow the pill for me? You'll feel a ton better if you do." He says. Bakugo pouts momentarily before putting it in his mouth and taking a massive, comedic gulp of water. Eijirou places the glass on the floor, and takes his boy into his arms. "Thank you, baby. Good job." Katsuki seems satisfied with the praise, and goes back to nibbling on his blanket, except this time he's pressed against Kirishima's chest. "I'm proud of you." Eijirou adds, just as Katsuki's thoughts are starting to tumble to daydreams. The blonde blinks at him. Their blanket corner drops from their mouth as they try to figure some big words to reply with. Kirishima can tell how hard they're trying.
    "Mm, love you." It's low and a half mumble, but Eijirou beams. He holds his boyfriend's face and pecks him.
    "Oh, you're so sweet, hm?" Eijirou teases. Katsuki's face gets pink, and he giggles, sticking his tongue out and smiling at Kiri defiantly.

    It's difficult not to regress when someone as lovely as Kirishima is assisting you to do so. Katsuki's able to melt into his arms like nobody else's, and that's why the idea of Kirishima leaving is so unthinkable - so horrific. He doesn't want to be mean; he doesn't want to be the villain in the Redriot origin story. But sometimes, he lets his anger take control of him.
    However, such mature thought is currently unreachable. Eijirou's hand combs through their blonde hair. "How about some hot chocolate?" He asks. Katsuki squeezes his blanket. Eijirou knows them so well. Bakugo nods, and reaches up, grabbing at Kirishima's face. Eijirou sniggers, allowing them to prod his cheeks and squish his nose. He's getting to quite like this side of Katsuki. "Okay, okay, hot chocolate coming right up, cutiepie." Eijirou says, rising from the bed, and half tearing Katsuki off of him.

    After the drinks are made, the pair huddle up on the bed, and watch some kids show episodes on Bakugo's laptop. "Careful, it's hot, remember." Eijirou laughs, right as Bakugo takes a sip and grimaces.
    "Ouch!" They whine, blinking at the mug with a disdainful puzzlement. How can such yummy liquid be so evil? Eijirou tuts, places down his mug, and tilts Katsuki's head up before kissing him gently. "You have to be careful with those lips, baby." He purrs, patting them on the head. Katsuki sighs, leaning his head on his boyfriend's shoulder. Their stomach has calmed, and with the cartoons, and hot chocolate, Bakugo couldn't be any bigger than four even if he tried to be.

A/N: I'm back with the next chapter... Finally, geez. I am convinced Kiri would use "cutiepie" constantly. It just feels like the Kiri pet name of all time.
