Dazai Osamu has been your roommate and best friend ever since you started your stage at your job. Your job wasn't easy, especially bc of you handling the finance business and making appointments to your boss plus having to fill STACKS of papers to the point you get home around midnight and wake up at 6a.m. He started growing worried seeing your tired face and not seeing you when he wakes up nor when he goes to sleep.
1:19a.m. he was at his desk doing reports of his job of a mission, his mind wandering back to you. Picturing your face so he wouldn't forget it 1:45a.m. his eyelids became heavy but they quickly shot to the door once he heard the keys turn the lock and your exhausted figure coming in - with locked eyes and silence, came a faint smile on his lips following with a small tired yawn "Oh hey~ I was worried about you.." he said, staring at you with tired sad eyes, his back leaning against his chair while playing with his pen.
