Kacchan wants Deku to move in & be his roommate cuz they already know each others ticks and says, 'you already annoy me and I know how to deal with it; you'd be an ideal roommate because of this.

Actually, he just thinks it will give him more opportunities to show the nerd he cares and to possibly even confess.

Deku wants to live with Kacchan because he /wants/ to live with Kacchan, except he /doesn't/ want to be roommates.

He declines the offer because he think it will hurt way too much to see Kacchan so much, to be so close, yet so far. If he can't be with Kacchan, there's no way he can /live/ with him, so he moves into his own place instead.

Kacchan says it's no problem, he'll make it fine w/ Shitty Hair and Dunce Face. "They're cleaner than you are anyway, Deku, as surprising as that is."

They still work together a lot and Kacchan invites him to hang out, to play video games and for dinner, but if it's at Kacchan's place it means the others are there too. Kacchan wants to hang out /alone/ with Deku but he doesn't feel confident enough to ask him out on a date.

"Yo, Kacchan, why are you in such a sour mood? You kicked all our asses in the game all night!" Kaminari teased after Deku left on one such night.

"Don't give him such a hard time, you know why..." he heard Kirishima say.

"Tch. What are you talking about, Shitty Hair?"

Kaminari's snickering in the corner.

"Come, on, man. It's so obvious."

"Spit it out!"

"You're totally crazy about Midoriya!"

Kacchan doesn't have a retort cuz Shitty Hair is spot on. He can tell from the scared look on Dunce Face's face that he knows too. So instead of yelling at them he just sighs.

"What should I do?" he asks.

"Well, for starters you should kick us out next time you have him over!"

Kacchan hadn't considered that because he didn't know they knew, but now that he did, he'd most certainly have to take them up on this. Why, in his mind, he sees this as easier than going /out/ with the nerd, he isn't sure. It feels more casual and more intimate at the same time.

"Alright, so next Saturday, make yourself scarce," Kacchan says.

He invites Deku over for dinner. Orders him his favorite take out. Cues up a movie. He talks himself up the whole day and takes deep breaths until he pulls open the door to let Deku in.

"Hey Kacchan! Oh, it's kinda dim in here."

"Is it?"

Deku pushes past and kicks off his shoes.

"Smells good in here, you burning a candle?"

Kacchan doesn't comment. Instead he tries to telepathically communicate /yeah it's supposed to be romantic./

Deku must have picked up the message because he starts to look a little nervous and oh god, this is what Kacchan was worried about; why he'd wanted them to move in together so he could slowly drop hints until Deku understood.

He knows that's not fair to Deku. In all other matters, Kacchan knows how to go for what he wants but he's feeling completely lost in this area. There's too much on the line and there's no way to train for it.

"Kacchan, where's Kirishima and Kaminari?"

"They went out. It's just me and you."

"Oh."

"Is that okay?"

"Of course! I didn't..."

"Deku."

"Yes?"

"I don't wanna lie to you." Kacchan suddenly makes the decision. No more putting it off, no more pretending. It's now or never and he can't do never.

"The truth is, I'm in love with you. I've been in love with you. That's why I wanted to move in together, so I could tell you without having to /tell/ you, ya know. But that's fucking cowardly. Not heroic at all."

"Kacchan. Are you messing with me?"

"No, Deku, of course not!"

"Because I love you too."

"You /what?/"

"I love you too. That's why I didn't want to move in. I don't want to be just roommates or just friends...I wanna be...more."

"You mean like this?" says Kacchan, moving swiftly to close the distance between them. He pulled Deku into a soft kiss, not knowing what the hell he was doing but letting his heart guide him.

"Yeah, exactly like that," answers Deku.

"So, then this is officially a date, Deku. I've got your favorite food here and a movie too."

Deku's smile took up his whole face and it made Kacchan's heart feel warm. He pulled him by the hand to the table and sat him down.

"This isn't my favorite food," says Deku.

"Hah?!"

"Your cooking's my favorite," he says.

"You don't have to flatter me, Deku, I already love you."

"I'm serious!"

"Well, anyway, I know you like this too. I thought it would be too bold of me to cook for you. I'm happy to be wrong about that."

"I'm just happy to be with you."

"With me," Kacchan says with a smile. "I like that."

"Me too. So this is just our /first/ date, right?!"

"Hell yeah. There will be many more, Deku. As many as you want."

"And how many more kisses?" Deku asks, cheekily.

"No limit," answers Kacchan. Deku beams.

"Good."

"Yeah, good."

And after a few dates and many kisses, Kacchan asks Deku to move in again. This time he agrees.

The End.
