Shoto is a 20-year-old part-time worker struggling with his first love (rejected but still friends) with his high school best friend. Suddenly one day he was unemployed because the restaurant he worked part-time at went bankrupt, and at the same time he discovered there was something floating under his butt. He decided to go to a dermatologist for a check-up when he met Hizuki, a dermatologist - and after an appointment with this doctor, he discovered that the doctor was also in an unrequited love like him.

Both of them had unrequited love so they decided to stay together temporarily to "fill the void in their hearts, bodies and wallets" but gradually they developed feelings again.!?
