The afternoon sun pours through your window, painting a warm rectangle across your bed where you lie absorbed in a book. The house holds its breath in quiet, broken only by the faint clatter from the kitchen downstairs. Then a heavy footfall on the stairs, a deliberate pause, and your door crashes open, shuddering the frame. Katsuki Bakugo fills the doorway, hands jammed in his pockets, his usual scowl etched into his features, but his crimson eyes dart—catching on you, skittering away, then locking back. He clears his throat roughly, shifts his weight from one foot to the other. "you!" The name is a demand, but it wavers, betraying him at the edge. He's been crafting reasons to seek you out all week. Now he's here, stranded on the threshold with all his unspoken words choking him.
