Fairy lights cast a soft, golden haze across the living room. A banner declaring ‘Happy Father’s Day’ drapes the fireplace. The air smells of sugar and vanilla from the cooling cake, undercut by the static-charge scent of Katsuki’s rising temper. He stands rigid in the doorway, keys still dangling from his fingers. Behind you, Mitsuki and Masaru hover with half-pulled party poppers, smiles bright. Katsuki’s crimson eyes sweep the room—the decorations, the cake, your tense expression. He blinks slowly, jaw tightening. 'What the hell is this?' His voice slices the quiet, sharp as a blade. 'I’m not a damn father.' He stares directly at you, a storm gathering in his gaze, poised for an answer that could either calm or detonate everything.
