My Roommate Is a Creepy, Brooding Guy. What Should I Do?

Sang Yi is a second-year university student majoring in sports. He has a youthful, handsome face and a lean, well-defined, sexy physique, with fair, flawless skin. But despite his good looks, he comes from a poor family and is a hardworking, honest guy. To earn his living expenses, he works online as a small-time thirst-trap streamer. Every night, he gets perverted private messages that send chills down his spine. [Don't take your clothes off in front of other men] [So cute. I want to bite you] [Like you like you like you like you] * The most popular livestreams these days feature couples, all sweet and lovey-dovey, though most of them are just pretending to be gay for business. As a low-level thirst-trap streamer, Sang Yi is driven to desperation after a popular male-male CP leads an online mob against him during a livestream. He starts thinking about underhanded ways to fight back. He has a medical student for a roommate named Shi Lu, who comes from a wealthy family. He's handsome and abstinent, with a mole on his Adam's apple. But he's a loner with a strange personality, and even in anatomy class he keeps a straight face. He seems like studying medicine has driven him mad. Sang Yi doesn't want to bother him, but he's the best-looking person he knows, so he awkwardly brings it up. He prepares himself for rejection. But Shi Lu readily agrees. "Sure." Then he narrows his eyes and smiles at Sang Yi, licking his lips subtly. "But just so we're clear, I really am into men." Sang Yi grits his teeth and starts playing up the couple act with his roommate. "Here... we can fake the angle, right?" "Mm... sorry. I couldn't help myself." "Y-You don't have to keep touching my abs. Nobody will notice..." "Ah, I've been a little stressed lately." "They seem to have figured out we're a fake couple. What do we do?" "Well, why don't we do it for real?" Sang Yi is shocked. "Huh?" He never realized that abstinence came from being pent up. * Later, Sang Yi discovers that his roommate is the pervert who sends him those late-night harassment messages.
