[Two heroines + city + stand-in literature + BE sadomasochism] "You said we used to have a close relationship, but I can't remember when I loved you." - Nan Shanxue was sure that she fell in love at first sight with Leng Qianyi, a roommate she had only known for one day. Nan Shanxue: "I want to try." Leng Qianyi: "What are you trying?" Nan Shanxue: "Let's fall in love with you." Later, Nan Shanxue discovered a secret. She and Leng Qianyi have known each other for a long time. They were lovers, but she was just a stand-in. It turns out that even three years can't warm a person's heart. Nan Shanxue wasn't sure if the "Axue" Leng Qian was talking about was herself. But she was sure that Leng Qianyi didn't love herself at all. She was extremely disappointed: "Let me go, I'm tired." This scene seemed familiar. This time Leng Qianyi locked her in her arms and said firmly: "I won't let you go. Nan Shanxue, don't even think about leaving me again! I love you, and you are the only one I love."
