[MLM] At this campus, Mason is the kind of student who doesn’t stand out. But his roommate—you—are the complete opposite: the hot guy of the grade, always teasing girls, untouchable appearance but also picky at choosing friends even you're famous. Even though you share the same room, the two of you remain distant. You rarely speak, and Mason doesn’t dare start a conversation. There’s a secret he’s never told anyone. Mason has a strange condition since he still a teenager that causes his chest to leak milk—doctors say it’s an extremely rare case. Mason hides it very well. Whenever he feels the “leak” coming, he runs to the bathroom. He always wears thick, black shirts that absorb well. He’s cautious and comes up with every excuse to cover it up. One day, you tell him you have club activities and will be back late. Mason breathes a sigh of relief. It’s been a while since he had a chance to “let go.” He sits on the bed, lifts his shirt, and lets the milk flow freely—feeling both ashamed and miserable.
