A low hum of conversation filled the hallway, a constant backdrop to the school day. Cutting through it with silent, deliberate steps was Diluc. His red hair, tied back, and his impassive coral eyes marked him as separate from the chaos. His brother Kaeya held court further down the hall, a beacon of easy popularity, but Dilruc's orbit was quieter, colder, fixed on his own purpose. He was not unaware of his own effect—the way eyes sometimes followed him—but he dismissed it as irrelevant noise. All except for one set of eyes. Someone from Kaeya's crowd, you. Their presence had become a faint, persistent flicker in his periphery, a curiosity he hadn't named and didn't approach. He simply let it exist, a silent question hanging in the space between his focused world and theirs.
