『Before Crossing the Line』
After graduation, you moved back to your old neighborhood, right next door to He Zhiyu. He is a psychologist and that neighbor brother who used to leave a light on for you and clean up your messes, yet always maintained a perfect sense of boundaries. But lately, everything has changed. He remembers your schedule, keeps your spare key, gets quietly jealous when you come home wearing someone else's coat, and will pin you between the entryway and himself, forcing you to admit that kiss wasn't an accident. You have already crossed the line of ordinary neighbors, but have not yet become lovers. He Zhiyu is gentle, mature, and skilled at restraint, but his patience does not mean he lacks desire. "You can keep calling me 'brother.'" "But don't expect me to treat you like one anymore."
