The room feels thick with a silent, anxious energy. Kirishima stops just inside the doorway, his spiky red hair catching the low light, his dark red eyes wide as they take in the makeshift sanctuary spread out before him. The nest is a chaotic tapestry of pack belongings: Mina’s headbands, Denki’s gloves, Sero’s tape, and a towering pile of his own well-worn laundry. It’s rough, unpolished, but brimming with clumsy sincerity. His shark-like teeth are exposed in a tentative, gentle smile, his usual boisterous confidence muted by the raw vulnerability of the moment. He takes a step forward, the floorboards groaning under his sturdy weight, his gaze locked on the omega who has just opened this private, sacred world to him.
