IT’S OKAY you just made it anon do not worry!!!!!
HInata would blush immediately. He would be really shocked, and would try to say something in return, but his mouth would just be opening and closing without any words coming out of his mouth, kind of like a fish. He would be overcome with embarrassment and also a warm feeling in his heart that leaves him smiling despite his entire face being red.
Kageyama would be pretty surprised. At first, he wouldn’t think it strange, assuming they might just be thinking about something he said and he would go over their conversation in their head. It wouldn’t be until noticing his crush’s obvious embarrassment that it finally clicks. Needless to say, anyone observing might think it’s Kageyama who was the one to say something embarrassing.
Tsukishima would be caught off guard, since he really hadn’t expected his crush to ever say something like that, and so bluntly (albeit shyly). He’d probably stare at them with a mixture of confusion, surprise, and something even he couldn’t quite place on his face. He would probably mutter something indifferent, but he would actually be pretty surprised and embarrassed, evident in his red-tipped ears, and avoidance of looking directly at his crush’s face.
Yamaguchi would be oh so embarrassed, but also incredibly elated. He thought the only reason his crush talked to him was for Tsukki, but hearing them practically admit that it was him that they liked was a huge, wonderful shock. In his excitement, he might blurt something out about how he was thinking of them too, then bite down his tongue because oh my god why did i say that.
Tanaka would stare at them for quite a long time. He’d be completely caught off guard because someone cute basically said they liked me and holy shit not just someone, but the person i like! There may be a minute or two of awkward silence that would have to be broken by his crush because Tanaka was still in such a state of shock. He may grow uncharacteristically quiet and shy, because is this really happening??
Nishinoya would lean closer with widened eyes and become super serious. He’d ask them to repeat what they said, and if they didn’t, he would grasp their hands and tell them to please repeat what you said please! When his crush finally does Noya would stare at them for a beat longer, before pulling away and feigning embarrassment. He would then smile and tell them that he really liked them, because of course this would be the perfect time for a confession.
Ennoshita would be pretty surprised, but he would be able to remain composed. He would probably mention that it was nice of them to keep him in their thoughts, and inwardly, he would be arguing with himself whether to confess right then and there. He would probably end up remaining silent about his feelings, but their words would prompt him to an invitation to talk to them more.
Sawamura would be completely caught off guard, to the point that if he was leaning on something he would have to catch himself or if he was drinking water he would choke and have to try not to spit it out. After he regains his composure, he would avoid any direct eye contact and glance to the side quite a lot. He would tell them that it was nice of them to worry about him to the point that he is on his mind (though of course he knew they didn’t exactly mean it that way).
Sugawara would be surprised, but he would try his hardest not to make things awkward for his crush. He would realize how embarrassed they must be or how much courage they had mustered to say it, so he would smile and tell them that it was sweet of them to think of him. He may quickly change the subject so his crush could feel more at ease, but he would have a wider smile than usual from his crush’s words.
Asahi would be extremely taken aback and very embarrassed. He would stutter and ask them to repeat what they said, just because he couldn’t believe it. He might even try to convince himself that they probably didn’t mean it that way, and that he was overthinking it, though secretly, he was really hoping his crush meant it that way.
Oikawa would grin immediately, and probably even laugh out loud. He would probably say how that was a good line, and that they really got him, but he would really be bubbling with happiness on the inside. He would tell them that he was thinking about them too, and the look on his crush’s face would be so priceless that the grin on Oikawa’s face only grew wider.
