Chapter 1: Karasuno first years with a crush

Chapter Text

Kageyama Tobio with a crush:
• Has no idea what the heck is going on for ages, just steals glances at his crush and doesn’t realize he’s blushing;

• He either figures it out because he googled it, or someone told him (Tsukishima or Sugawara said something to tease him and found it hilarious when he genuinely had no idea what they were talking about);

• He finds it kind of annoying once he knows what’s going on because it takes up so much space in his head. Thinking about how cute and attractive they are means he isn’t thinking about volleyball or trying not to fail his academics, and no, he cannot multitask unless it involves volleyball;

• He got this crush because they spent hours studying together, so now he doesn’t know what to do because studying with them no is damn near impossible when all he can think about is how nice their hair smells, his grades are dropping, his team and his teachers are on his ass and the one person who could help him is the entire reason he’s in trouble in the first place;

• Please, help the boy, he’s short-circuiting every time he looks at you, for the love of everything corner him somewhere and get him to spit it out;
• Tobio had never been a huge thinker, especially with things he knew nothing about, like crushes, so when everyone tells him that the solution is to come out and tell you, he just goes ahead and does it;

• Did he expect to get a romantic partner out of it? No. Is he incredibly happy about calling you his? Absolutely. He now has something to brag about other than volleyball, and as for studying, he sits closer so he can smell your hair, even run his fingers through it if he’s feeling bold, and now it actually helps him focus;

• Kageyama Tobio is hopeless at relationships, but his feelings are always sincere, he’ll learn your every tell and quirk, especially the ones that mean you’re sad. When he knows you’re having a bad day, he knows the solution is simple, all he does is open his arms and speak softly “do you need a hug?”

• It’s his go-to move, and he loves doing it, because it makes him feel needed.

Tsukishima Kei with a crush:

• A crush for Kei only comes after knowing someone for a good long time, and I mean years here;

• He’s not one to trust easily, and for anyone to be on the “romantic radar” for him, he has to know them like the back of his hand, and yes, he’s aware that this means they know him just as well;

• He likes that they know him, he likes that he can’t lie to them, he likes that they’ve grown thick-skinned to his insults and give as good as they get (because come on, being his friend for years means you’re a sass master);

• He’s seen sides of you that no one else has, and knows the very second he started looking at you as more than a friend;

• The moment had probably been nothing special, just walking somewhere or eating lunch together or something you did together literally every day, but for some reason, that moment had made his chest ache, and from then on, he knew he was doomed;

• He immediately begins playing with the idea in his head, of having a romantic partner at this point in both of your lives, because he knows your every struggle and ambition, he will not act on the crush unless he feels like it won’t hinder either of you;

• Let’s be honest, he’s a pessimist, so of course, he’ll fill his head with all of the worst possible outcomes, and ultimately the fear of losing you will put an end to any courage he might have built up to talk to you;

• He’s a good actor, comes out the next day like he hadn’t spent the entire night overthinking a relationship with you, and he doesn’t mention it to a soul, not even Tadashi;

• As far as he was concerned, he’s made up his mind, accounted for every variable…except you;

• No matter how long he’d thought about it, no scenario he had dreamt up had actually involved you, confessing to him with a handmade gift in your trembling hands;

• Calculations and worst-case scenarios are damned, he couldn’t say no to you, couldn’t subject you to the very rejection that had stayed his hand in confessing himself;

• He’d never forget the feeling of kissing you for the first time, he’d stolen your lips the very second after your confession had left your lips, and that little handmade gift you gave him hadn’t left his person for a single second since;

• He went on, admiring you for having the balls to do what he couldn’t. You’d never know about his hesitation, you’d never know that if you hadn’t confessed that day, you wouldn’t be wearing that ring on your left-hand years later.

 

Yamaguchi Tadashi with a crush:
• Credit where credit is due, Tadashi has a gift with people, he’s empathetic and self-aware, but he’s also rather self-conscious;

• His crush is someone he admires, professionally, academically, innocently, at first;

• They’re someone who never underestimates him or compares him to the other first-years, and before he knows what day it is, he’d in deep;

• His face always feels warm when they’re around, he’s ashamed of how quickly he fell for them and tells himself that someone that perfect would never even look at him that way;

• As time goes on though, his team helps him become more confident in himself and his abilities, but outside of serving in volleyball, he’s just…Tadashi, nothing special about him;

• The big game-changer came when his crush comes to one of Karasuno’s games (he doesn’t notice them until after the game, thankfully or he would have given himself a nervous breakdown);

• He aced his serves for that match, he scored more points for the team than he ever had before and he was walking on clouds long after the match was over;

• For his actions when he saw his crush, he blamed adrenaline, and them, for pulling him into a hug, even when he was all sweaty and in uniform;

• They told him he was amazing, they told him how proud he made them, singing his praises in his ear while their arms were wrapped around him, he couldn’t have stopped his next words if he’d tried;

• “I have a massive crush on you!”

• He’d said this a little too loudly, in a public hallway, surrounded by his entire team who were very much staring at them now, and…oh god was he hyperventilating again?

• He thinks it’s been ages, but in reality, their answer was swift and doubtless, spoken with a smile to light up the world and followed with a kiss to his cheek;

• “Good, ‘cause I’ve got one on you too! Ice cream?”

• “Huh?!” he croaked, staring at them with wide eyes, hands awkwardly placed on this hips, rigid as wood;

• “Say yes, Yamaguchi.”

• Reflexively, he nodded at Tsuki’s words, his crush giggled at pulled away, telling him they’d be waiting at the gate, leaving Tadashi to be mobbed by his rabid senpais that were so incredibly happy (and highkey jealous because you’re hot af);

• He became such a picture-perfect partner, and though he needs to be reminded that you want him, not someone else, the same way he grew confident in his serves, he grows confident in the relationship and makes you proud to call him yours.

 

Hinata Shoyo with a crush:

• Ball of sunshine, he’s a social magnet, drawing people in everywhere he goes, it’s no wonder half the setters in Japan want to set for him;

• He meets his crush through volleyball (because of course, he does), they’re on a team themselves, a libero;

• He sees them practicing with some of their team, ends up joining in, and learns that you can set as well as dig up just about any ball;

• He doesn’t realize what’s happening until he starts looking out for you at training camps, texting you every day (because of course he got your number the first time he met you);

• You offered to practice with him once or twice a week because according to everyone, his receives sucked, who better to help him than a libero?

• Once again, he doesn’t realize that those times, alone with you in his back garden, just passing a ball back and forth, had become his happy place, whether you were quietly guiding him or joking around, he felt secure;

• The crush itself didn’t come in until later when he started seeing you as more than just a safe place and a way to learn;

• On a bus ride back to your place, you offered to share your music, and he learned what you liked to listen to, a glance at your room told him what you liked to read, what posters you had up, your favorite shows, the food you hated;

• It was all these little things that piled up, he didn’t realize what was happening until he was reciting your favorite order at a restaurant he’d only been to once before you’d even opened your mouth;

• That moment felt so right to him, he didn’t want to seem domineering and instantly apologized for ordering for you, but the second you told him that this was in fact, what you’d been planning to order, he smiled;

• He asked you out the literal day he realized he had a crush on you, come on, this is Hinata, overthinking is not his thing;

• The next time he was at practise, he made sure his entire team was aware that “his partner was just as awesome a libero as Noya-senpai!”

• If you want to fluster him, ask him “only just as awesome?” Bonus points if Noya is nearby because he can’t wait to watch his underclassman trip over his words;
• After that, he switches to saying “my partners definitely the cutest libero though, no offense senpai!”
