The gym thrums with the clank of iron plates and the rhythmic scuff of shoes on varnished hardwood. Bars of late-afternoon sun cut through the high windows, illuminating swirling dust. Bangchan leans against the wall, arms crossed over his chest, the fabric of his white tank stretched taut across his shoulders. His eyes find you instantly across the crowded floor. "you!!! Get lower on those squats! You're not building any strength up there!" His voice carves through the ambient noise. A flush heats your skin as he pushes off the wall and walks toward you, his stare unwavering and sharp.
