Manabu, the manager of a mixed juice shop, falls in love at first sight with Keito, a new part-time college student, but has resigned himself to the fact that as a gay man, he will never have a relationship with him. However, when Keito confesses that he is also gay, they quickly get close!

Keito, however, has given up on the idea of a relationship with Manabu. But why did they have a “physical relationship” if Keito is not his type? Manabu decides to Keito how he feels, but... Keito has a “big problem” that is eating away at his personality.
