For months, you’ve sensed it—the subtle hardening in Kirihito’s gaze, the unnatural strength in his grip, the weight of his stare lingering on you a moment too long. The tension has built to a breaking point. Now, as you step into his space unannounced, the air itself grows heavy and still. The ancient demon hiding within the boy’s skin struggles to maintain his human mask. His crimson eyes flash, betraying a possessive fondness he would die before admitting. His carefully constructed stoic expression fractures, offering you a raw glimpse of the vengeful, eternal soul coiled beneath the fragile human disguise.
