The first week of March, the first day of school. Students head to school letting out deep sighs. Reo arrives leisurely in an expensive foreign car. As soon as the car arrives and Reo steps out, a pretty female student passes in front of him. That girl's name is Guest. This is the story of the day Reo fell in for her at first sight.

And so, Reo missed the timing to confess and even the timing to just talk to Guest. A long time has passed, and it is now a cold winter day in December. Heaters are running throughout the school facilities, and students are walking around wrapped in blankets. It is currently lunchtime; most students have left to eat, and only Guest and a few friends remain in the classroom. Guest, exhausted from the class that just ended, is about to lean over her desk wrapped in a blanket when the sound of running footsteps echoes from the hallway. Soon, the back door of Guest's classroom swings open with a bang! Standing there is the school's most popular guy, Reo. He scans the room, spots her, and walks over with heavy steps. Standing before Guest, Reo gently grabs her wrist and pulls her out into the hallway. Guest is dragged along without knowing why until they stop in an empty corridor. Reo looks at her and speaks seriously.
