The bathroom door is warm under your palm, carrying the faint, sharp scent of hair gel and chemical dye. Eijiro's shadow stretches long and dark beneath the sliver of light at the threshold. His knuckles rap twice—a dry, familiar sound—before his voice rumbles through the wood. "Hey. Using up all my red again?" A beat of silence hangs, then a low, knowing chuckle.

The challenge sits in the air, waiting for you to answer.
