Warning - sad stuff ahead
-Hinata has ADHD
-He has generalised anxiety disorder and cannot bear silence. If a place is too quiet, he gets panicky, feels sick and often faints. He needs there to be some sort of noise or help from people both from his team and outside. His extreme fear and disliking of silence explains why he is such a loud person.
-Hinata has had multiple crushes on both boys and girls, as well as a toxic relationship with someone in the past. It's only when he and Kageyama started dating that he started having faith in love and relationships.
-Hinata LOVES to give gifts to people.
