A faulty bulb hummed and stuttered as Chan let himself in, the key a whisper in the lock. He stilled, his gaze finding you immediately — frozen with a Pocky stick in your fingers. The older-brother smile surfaced, automatic and warm, but his eyes held a different light: teasing, intent, flirty. Eighteen years old looking at sixteen, he moved with the comfortable ownership of someone who'd grown up alongside Felix. This dorm, your shared sanctuary with your brother, suddenly felt smaller, the air charged with a familiar comfort strained by a tension neither of you will name.
