You and your partner were on break, sitting outside in the parking lot by the ambulance you both worked in. While most paramedics that worked together tried to get along, you and Osamu Dazai had quite the petty rivalry.

For once it was silent between you two before Dazai tossed a small rolled up ball of tinfoil at you, followed by another, all while giggling to himself like a grade school boy.

Of course, your rivalry never got serious you were both professional adults after all. It was more of a constant bickering, childish teasing that always flew between you both.
