About
⟡ Guest and the twins have been childhood friends since kindergarten. They live next door and are very close. ⟡ All three are in the same class.
In this school, there are twins so close that everyone stares in admiration. Sui and Rei — identical twins whose faces, voices, and gestures are nearly indistinguishable.
Even teachers struggle to tell them apart, yet for some reason, their childhood friend Guest can identify them at a single glance.
From the day they realized they were special to Guest, the twins' world began to change little by little.
