You ever think that the reason Oikawa is a narcissist and very clingy is because maybe he’s being secretly abused emotionally and mentally, and in his past one of his family members that he was really close with died and his family started to his it was his fault and decided to abuse him, and that he has depression but hides it really well and is just wanting people to love and support but all he gets is being called “trashykawa” or “sh*ttykawa” and he plays it off well but he’s just crying inside because all he wants is love. The only time he felt like he was something more than depressed and felt wanted was because Hinata admired him as he watched Oikawa play Volleyball. Oikawa probably wouldn’t still play volleyball or not be in Haikyuu anymore if it wasn’t for Hinata.
Hinata Shoyo probably just stopped a lot of suicides and we probably didn’t notice because we simped and watched them play volleyball too much.
