"Seriously," Touya leans on the door frame of Natsuo's room, self-satisfied smile on his face "You're crushing on...Shouto? Our Shou-chan?"

You cover your face with despair at your predicament. You can't believe you're actually telling either of them. It wasn't like you were planning too. In what universe would you even think to do that deliberately?

But Natsuo is frighteningly good at grilling you about things when you refuse to tell him. Ever since he found out about your crush, he made it his lifes mission to harass you about it. You were careful, damn it. You didn't even actually tell him, he used to his annoying deductive reasoning to figure it out. You tell Natsuo everything.

He knows about every weird medical problem you've ever had, every partner you've ever dated, and every weird fit of crying you've ever cried in your life. He's your confidant. Your best friend. So he knows there's only two sorts of crushes you couldn't tell him about.

If it was on an ex or if it was on one of his siblings. His first guess was Touya - but he figure you wouldn't be this embarrassed about that since you often wolf whistle at him when you're in the house.

Then he guessed Fuyumi, because you're still embarrassed by how pretty she is. When you said it wasn't her - he was briefly stumped before settling in a shocked silence.

"...Are you crushing on Shouto? Seriously?"

Your embarrassment told him he was right, and now you're sitting in his room and hoping the world will swallow you because you're crushing on your best friends little brother of all things.

In your defense, it wasn't always like this. You didn't see much of the youngest Todoroki at all growing up. He was in his dorms for most of highschool and Natsuo spent most of his early adulthood ducking his parents house entirely. You only met him properly when he turned twenty. They're only living together now for Touya.

You kind of wish they weren't - since it'd save you the trouble of being embarrassed twice. You've been seeing Shouto a lot recently, since you've been coming over to hang out with Natsuo.

Shouto is not the 16 year old boy you always made. He's 22 and he's got tall and lean muscle. He's polite but sweet and strangely - much funnier than you could've ever predicted. He's genuinely very kind but most of all - he's been very direct on telling you that he likes you.

You don't think anyones ever pursued you like this in your life. Both of your last relationships ended amicably but neither of them had been this...direct with you ever. Shouto is very direct, actually. Direct in telling you which honorifics to use, and telling you how nice you look, and saying he misses you often. You've been dismissive. Even you're not so desperate as to openly pursue your friends little brother.

But again, he's not so little anymore. He's taller than you now, and he's got lean muscle. He always smells great. He is incredibly pretty in the fairy prince kind of way. This is by far the worst crush you've ever had to endure in your entire life. You've tried to forget.

But just last week he walked you home after patrols, speaking casually and kindly and good god - what is with the broad-shoulders? When did that even happen?

You want to die. You want to disappear into a black hole. You want to scream and cry. Why you're crushing on a boy 4 years younger than you? Why is Todoroki Shouto of all people make your heart flutter?

"Seriously... I mean I knew he was flirting with you pretty brazenly but," Natsuo looks like he's holding back a grimace. If you weren't holding back tears, you'd hit him "...Shouto? Like...really?"

"Didn't know our little angel was such a casanova. Crazy world we live in."

"Neither of you are helping." You say exasperated. Natsuo leans back on his palms, sighing a little. "Do you think I wanted this?"

"It's not the end of the world," Natsuo offers thoughtfully. You give him a meaningful glare from the corner of his bed but he doesn't budge "I mean..I guess if I got to pick who he dated, you're not at the very bottom of the list."

You kick his side. "That's so backhanded."

"He doesn't want to admit you two are a good match," Touya says thoughtfully, unwrapping candy from his pocket. A habit he picked up trying to quit smoking "He'll be lonely if you date Shouto."

"Shut up, Touya."

You ignore both of them for a minute trying to get your bearings.

"You think we're a good match...?"

Touya laughs hard "Is that all you heard? Poor Natsu, already being abandoned."

Natsuo shoots Touya a glare.

"Touyaaaa," You drag, reaching over to tug on the bottom of his shirt "Elaborate."

"And feed your delusions?" He says, clicking his teeth "Fine. Only because it's funny."

Natsuo hmphs, and you look at him apologetically. You two will have to talk about it later. Touya rolls the candy in his mouth, pulling his shirt up to scratch at his abdomen.

"Dunno. You're like... probably one of the only people who's not gonna treat him weird cause he's a good little hero. That brat... it's probably best for him to date someone normal and civilian-esque. Not like being a hero is the most important thing in the world to him."

You flush a little. This is really, really bad. Natsuo gives you a disapproving look. You look back at him a little softer.

"I won't date him if he's off limits." You offer. Touya coos at you both.

"Well aren't you darling."

Natsuo groans, laying flat on the floor.

"Ugh. It's not like I can just say no. It's enough of a miracle that Shouto is showing interest in anyone. And if he misses out on true love, even if it's," He gives you a sideways glance and shakes his head "Even if it's with you then I can't actually stop it."

"I'll reject him if you tell me too."

"What kind of older brother do you take me for?"

"Yeah, what kind of older brother do you take him for?" Touya mocks, laughing to himself "Aren't you just a saint, Natsu?"

"Touya, I'm gonna throw you out of my room."

"Ooh, someone's mad."

Before Natsuo as a chance to come back, the sound of the door opening from the living room downstairs floats up. Shouto calls out. You feel your heart almost fall out of your ass. Touya, delighted, is the first to reply.

"Shou-chan, we're upstairs."

You make a gesture of violence towards Touya who replies by pretending to jerk off then giving you the middle finger. You don't have time to collect yourself before Shouto is upstairs. He's back from patrols and he's a little sweaty. You feel heat creep-up up your neck.

"Touya-nii, do you still—oh," Shouto smiles soft as he realizes "It's you. I didn't realize you were here."

"I came in after class."

"Alone? You should've asked me to walk home with you."

You flush. Touyas' snickering is not helping you at all.

"Isn't that out of your way?"

"It's fine. I do stuff like that a lot," You're almost disappointed until he tacks on "But it's you so it's alright."

You look up at him wide-eyed. He gives you the ghost of a smile. God you're screwed. Before you can reply, Natsuo clears his throat.

"Go wash up. You stink." He chides. Shouto immediately goes back to being a little brother, nodding his head.

"Okay. Then," He looks at you directly. You're so screwed "I'll be right back."

You wait until Shouto is finally down the hall, listening for the bathroom door to thump shut before falling back into Natsuo's bed. Touya breaks out into a fit of laughter as Natsuo sulks in the corner.

But all of it feels like white noise when you compare it to the sound of your heartbeat, thudding hard in your chest.
