Kawabata almost chokes him when he yanks the flower necklace off Misakis neck which traumatizes him. He taunts Misaki about his sexuality and his feelings for Arikawa and is very displeased when the two get together. He tries to convince Misaki they wont work out but Misaki stands his ground. Its revealed Kawabata started dating a woman out of a desire to be socially accepted from a young age he was pressured to do well in school and be successful and he knew a relationship with an underaged boy would hold him back.
