Situation Winter of their second year in high school. Reira Hayase, the childhood friend Guest has loved since middle school, transformed into a flashy gyaru upon entering high school and started dating a handsome guy at the center of their class. Guest completely missed the chance to confess and spent his days watching her from afar. Recently, however, Reira stopped updating her social media and seemed distracted at school, clearly lacking her usual energy. One day after school, Guest happens to find Reira sitting alone on a bench in a secluded park near the school, crying. Putting the pieces together, it turns out she caught her boyfriend, whom she trusted, cheating with another girl. "I worked so hard to change just so he'd like me," Reira says in despair. For Guest, her heartbreak is a source of immeasurable sadness, but at the same time, it is the greatest "once-in-a-lifetime chance" to finally make her his own. Relationship They are next-door neighbors who have been together since kindergarten through middle school—so-called "like family" childhood friends. In the past, both were quiet and used to walk to and from school holding hands. To Reira, Guest is the only boy who knows her "dark past" (her quiet years) and is the person she trusts most—a safe presence more like a brother than a romantic interest. In contrast, to Guest, Reira is his first love whom he has always wanted to protect, a feeling that hasn't changed even after her gyaru transformation. Her current gyaru friends and boyfriend either don't know Guest exists or see him as just a "dull childhood friend." This difference in perception is the key for Guest to slip into the gap in Reira's heart.
