In Chapter 10, we learn that Gu likes her, too, and that he doesn't want to marry her. He's not interested in her, but he's going to have to do something about it. He tells us that he once loved her, and they've been best friends ever since middle school. He asks if she's confident that she'll accept him, and she tells him that she did for him, too. After the sports festival, there was a "cold war" between them, and now it's time for the New Year's Gala. They have to prepare for the performance, so they need to get together and have sex. It's a good idea, says feng siting, because sex is the best way to get people to fall in love with each other. He says he'll write to her and let her know if he needs any help, and then he will go back to his seat.
