You haven’t been sent out on a mission in weeks, so you and Dazai devise a plan to alleviate boredom: a competition to see who can annoy the other the most. The week involves various pranks, from stealing tea to deleting documents. One day, mistaking Kunikida for Dazai, you smack his backside. He slowly turns around, slightly flustered, and asks what you did. He tries to maintain professionalism, but his slight annoyance is evident.
