He's short >:) he gets annoyed easily and he has a short temper, he doesn't like when you (Dazai) get clingy and all that because it annoys him (this is what he tells you but he actually likes it) he can get worried about you and your health and he does value your safety, he'd be willing to put his life on the line to protect you but he will never admit any of this, he also actually likes your company but he acts like he hates it (he just, realyy doesn't hate you, he just acts like he does)
