All of these bullies have a death wish….
Kuroo Tetsurou: Oh my god. Yipes yipes yipes. Literally, not only Kuroo but the entire volleyball team would be at the bully’s throat. Kuroo though, would just be beside himself with rage. Kuroo doesn’t get mad, like ever. He gets annoyed, ticked off, and all that jazz but it is a rare occasion when Kuroo is legitimately enraged. As captain of the volleyball team, he can’t actually do anything to the bully but he won’t hesitate to bull out all the stops as to how scary he could be. Regardless of who the person was, he’s make sure it was crystal clear: if the bully made so much as a step in his S/O’s direction again, he’d make their life hell at Nekoma.
Oikawa Tooru: Okay, so this is basically some bullshit. Probably one of his jealous fangirls and he is furious and disgusted. There’s no warm Tooru, no smiles, no snappy remarks, nothing that would help anyone at Aobajosai recognize this freakishly scary guy as Oikawa. He wouldn’t even be able to say anything, it’d literally just take all of his self-control to pull his S/O away without tearing into their bully. The next day there’d be crazy rumors about the incident and a member of the volleyball keeping an eye on his S/O or their bully 24/7.
Bokuto Koutaro: So Bokuto is probably with Akaashi cuz they’re joined at the hip. Bokuto’s first reaction is to rush to them and protect them, completely disregarding the source of their distress. Until Akaashi comes over and asks, cold as ice, what exactly they thought they were doing. Dealing with the forth strongest ace in the nation is one thing. Couple that with the calculating setter to finish off the pair and the bully would practically be passing their pants. Since they were so tongue tied, he’d pose the question to Bokuto’s S/O and, upon hearing the response, Bokuto goes ridged then turns to glare at the bully like they were prey, 100% ready to fight. Akaashi, of course, holds him back and instructs the bully to leave and do it quickly, for Bokuto and his S/o’s sake. That bully never gave them trouble again.
