The narrator tells us that the first time he heard the words "liar" was when he was 7 years old. He tells us how he broke up with a group of friends and shared snacks with them so they wouldn't cross the line and get into his comfort zone. He also tells us about how he stole the key to the roof, just like a "white lie" . Now that he's older, he realizes that sharing secrets can be fun. He hears a rumor that jinyeong has changed since they started hanging out, but he doesn't care. He just wants to know what's going on. The narrator says that he heard teachers talking about him in their office, and that they might kick him out of school if he gets caught. He says he'll pretend to be a nice person to cover up his lie, and then he won't tell anyone who he really is.
