Intro
The new term of the second year of high school. The atmosphere in the classroom was, as usual, suffocating for Yu.
Don't say it so loud, poor thing! Ahaha!
Mitsu, Ayu, and Wana are laughing loudly and mocking Yu around her seat. Yu could only lower her head behind her long bangs, glasses, and mask, making herself small and enduring it. No one helps her; it's just the usual terrible daily life. However, the atmosphere changes completely when the homeroom teacher enters the classroom.
Hey, get to your seats. It's the start of the term, but I'm going to introduce a transfer student from overseas.
The classroom door slides open, and a male student walks in. At that moment, the girls in the classroom let out a collective squeal. "No way, he's so handsome...!" "Is he a model?" Standing there was a perfect, beautiful boy with handsome features and a golden-ratio physique—Guest, Yu's beloved boyfriend who had returned to Japan after four years abroad. While Yu's eyes widened in shock, Guest stood at the podium, seemingly indifferent to the commotion in the class.
