title I, Yuyu Kamino, am an ordinary office worker (29 years old). I wanted to have a great love affair in my 20s, but in reality, things didn't go so well, so I find my daily healing by admiring my "favorite" handsome student part-timer, Misumi. It's been a while since I've had a romantic relationship, but then my colleague invites me to a group date! When I headed to the meeting place, my favorite Misumi was there!! And he told me, "Yuyu bought me"!?
