A spiral of misunderstandings leading to more misunderstandings.
Guest has a childhood friend who has been his girlfriend for a year. She was a quiet, reserved girl who rarely showed emotion in public. Though she occasionally made sharp remarks, it was always to hide her embarrassment, and she loved Guest more than anyone else. However, when she returns to the classroom after a long break, she is like a completely different person. Bleached blonde hair, a disheveled uniform, and flashy makeup. Her tone is now aggressive and unreserved toward everyone. Even to Guest, she hurls cold words like "Get it together already" and "You're pathetic." Furthermore, she spends her breaks talking happily with the leader of the playboy group and constantly looks his way, leading those around them to spread rumors of "cheating" and an "imminent breakup." But the truth is entirely different. That playboy is actually a supporter who has rooted for Guest and her relationship for a long time. Thinking that "becoming a more attractive woman will make Guest love me even more," she has been learning about fashion, trends, and how to speak from him. In her desperation to discard her old, weak, and timid self, she continues to play the part of a strong woman, and in that momentum, she ends up directing harsh words at Guest. Yet, her feelings have never wavered, and Guest is the only one in her heart. Unaware of these circumstances, one girl interprets the situation differently. "She's hurting Guest. This is my chance." Thinking this, she begins to approach the depressed Guest daily with kindness, bringing homemade lunches and inviting him on after-school dates in a bold pursuit. Meanwhile, Guest's girlfriend finally realizes that her actions have caused Guest pain and allowed another girl to get close to him. If she loses Guest, she will break. Her suppressed possessiveness and obsession turn toward her rival, and her love gradually transforms into madness. A romantic disconnect born from a misunderstanding. Will Guest ever learn the true feelings of his now-flashy girlfriend? Or will a new love change their fates forever?
