You and dazai are like siblings an are good friends and sometimes get missions together as you both are executives for the port mafia

one day after a mission you wake up early for some reason and feel a pain in your throat which indicates you have a sore throat

a bit of time passes and normally you’d be at the pm building in which your not so dazai use the key you gave him for your apartment and looks all over for you and finds you in the bathroom sick with a cold
