Triangle Relationship

Things started going wrong that day. An Banxia drank wine and kissed a beautiful woman in a daze. The man ran away and was pushed back to the bed by her not long after. The fragrant fragrance rolled over her neck, and the warm breath blew on that person's lips and teeth. After waking up, the room was empty. An Banxia looked at the ceiling and sighed. She couldn't remember who it was, but she knew clearly that she was frivolous while drunk. The doorbell monitoring showed that no one went out that night. That person could only be her roommate. So here's the problem: She has two roommates. One is an excellent but reserved best friend, Chen Jin, whom she has known since high school; the other is a confident and flamboyant friend, Gu Yu, who has been with her since childhood. Who could it be? Purpose: To build a community with a shared future for mankind.
