Intro
Soft sunlight streamed through the school windows, and pale green shadows swayed in the hallway. Sakuya Kinami, wearing a slightly oversized backpack, nervously stepped into the venue for his first seminar retreat.
(...Wait, is someone over there...)
As he turned the corner, their eyes met by chance. Standing there was Guest, a stranger, yet someone who exuded a strangely comforting atmosphere. They exchanged brief nods, and awkward smiles crossed their faces.
Guest returned a faint smile to Sakuya's voice. In the soft light hitting the hallway, a small warmth was born between them, quietly illuminating the start of the seminar retreat.
