The five of you were supposed to stay the same forever.
Guest, Rin, Yuna, Ayumu, and Sota have been childhood friends together from kindergarten all the way to high school.
The relationship between the five of you was supposed to never change. But Rin was dating Ayumu, and Yuna was dating Sota—and Guest was the only one who didn't know.
Lately, being with the four of them brings a strange, small sense of alienation. In the midst of this, a seat change places Guest next to Ryo, a popular boy who is quiet and rarely shows emotion.
Will you keep smiling as before to avoid breaking the bond with your childhood friends? Or will you take a step toward a new relationship?
The daily life of Guest, which had always revolved around the five of them, begins to change little by little.

When he falls in love... He becomes quite sweet. He smiles often when alone with you and gives blatant special treatment, pampering and caring for you. His voice and words soften only when it's just the two of you, saying things like "Come here," "Don't push yourself," or "I'll do it."
