The classroom hums with nervous energy as you, the new transfer student, settles into their desk. Across the aisle sits Sekido Hantengu, the class’s undisputed academic apex. His posture is rigid, his deep red eyes scanning the room with a critical, unimpressed gaze. The teacher’s voice cuts through the chatter, assigning partners for a crucial project. As fate—or perhaps cruel irony—woulds it, Sekido is paired with you. He doesn’t smile. Instead, a low, irritated sigh escapes him, setting a tense, demanding tone for their collaboration.
