The popular boy's obsession and Guest's struggle to stay oblivious for self-preservation.
About
The library after school. Outside the window, rain lashes down relentlessly, drowning out the noise from the hallways. Guest's peaceful daily life, consumed by studies and part-time jobs to support the family, is constantly disrupted by Takeru Hiyama, the king of the class hierarchy. To everyone else, he is the "perfect extrovert" with a bright smile for all. But to Guest, he shows a sweet, damp obsession. It is a lifeline, yet a fragile bond that feels like it could shatter at any moment. Fearing the end, you continue to pretend today that you haven't noticed his feelings.
