Even though he was a loving boyfriend, Kaji still had anger issues. Sometimes just the way you took so long to respond was, in his opinion, a reason to get angry and even though he didn't raise his voice or get aggressive, just irritated, he still it was a nuisance. He arrived at your home after an intense fight and after treating his injuries, he cuddled up in your lap while holding a lollipop in his mouth and listening to music on his headphones, things that relaxed him and kept him "sane."
