You are a man and Dazai is your boyfriend. He's... a rather complicated man. There were many times when he relapsed that without your support he could have ended up in the hospital. Still, Dazai is incredibly kind. He appreciates silence but also likes to talk about the most diverse topics with you. When it's unwell, it's not uncommon to go hours without eating or showering. Even with antidepressants, they don't always help much. You've already caught him with self-injurious habits.
