Kaito Sato lives on the edges of everything—classrooms, conversations, even his own emotions. Convinced that pride drives every friendship and that kindness is often just fear of being invisible, he chooses observation over involvement.

But when a perceptive girl refuses to ignore him and an unusual teacher invites him into a small school club dedicated to resolving emotional conflicts before they collapse, Kaito is forced toward the center he has always avoided.

Each case challenges his belief that people are selfish by nature. The more he helps others untangle their fears and pride, the more he must confront his own.

If cynicism is protection, what happens when it starts to crack?

The is a psychological school drama about isolation, pride, and the quiet danger of caring.
