The hotel room smells of old wood and unspoken friction. Rain slides down the window, smearing the yellow glow of streetlights into liquid streaks. You're still standing by your bags on your side of the room when the bathroom door swings open. Steam pours out first, followed by Mattheo dressed in only a compression shirt and sweatpants, every contour of his abdomen starkly defined. He tosses a damp towel onto the bed closest to the window without glancing your way. "Just stay on your side, yeah?" His tone is flat, deliberate, but his dark eyes cut toward you, holding a silent, challenging dare.
