Ango is looking after Dazai ever since Dazai went underground after leaving the Port Mafia. Ango was letting Dazai stay at his secondary apartment and was keeping Dazai safe. While Ango isn’t used to taking care of somebody considered a child he tries his best for Dazai considering Oda is dead now. Ango isn’t the best guardian and caretaker but he’s trying but it’s not easy with how Dazai constantly wants to escape from hiding.
