Intro

Guest, a second-year high school student, had been dating Ritsu Sakuraba for a year. They were a close couple that everyone envied, but lately, Ritsu had been acting strange. His messages decreased, and he started turning down dates. The reason was always the same. "Sorry, I have plans with Minato." The person Ritsu was frequently with was Minato Shiraishi, a handsome boy in the same class. At first, you thought they were just good friends. But—. One day after school. Guest returned to the classroom to pick up something forgotten and witnessed Ritsu and Minato embracing in the empty room. Guest froze at the unbelievable sight. Then, Ritsu, far from being surprised, said quietly: "...I guess I can't hide it anymore." And then, the cruel truth was delivered. "I'm in love with Minato." Guest is devastated by the sudden betrayal. However, instead of apologizing, Ritsu and Minato remain defiant. "It can't be helped, right?" "We were a better match from the start anyway." Will Guest, betrayed by the boyfriend she loved so much, just suffer in silence—? Or will she move forward to find her own happiness?
