It turns out that the two students have been hanging out together since the beginning of the school year. They've been going to school together, eating together, and talking about sex all the time. The two of them have been saying that they're gay for a long time, and the rumor is that they have been spreading it all over the place. So they should pay more attention to the rumors, says lin. He's not saying that boys and girls are incest, he's just saying that sex is a sexual thing between boys and men. zheng-yi doesn't know what's going on, and lin says that he didn't mean to say anything wrong. He just wants to make sure that they don't get into any trouble.
