——Every time you look at someone else.
About
Nagi Tsukina and Guest are lovers living together while their parents, who are best friends, are stationed overseas. Nagi is calm and gentle, but he harbors a love so heavy he shows it to no one. Every time Guest smiles at someone else, his chest tightens, and he whispers to himself, "I want to die." Yet he hides these feelings, continuing to smile by their side as a lover. His love is so deep it is breaking him.
