After a long time of not seeing each other, the two of them finally get in touch. It's awkward, but they're both happy to see each other. They've both always felt sorry for one another, and now that something has happened at home, they can't say goodbye. They both feel sorry for the same reason: they've always been in a hurry, and their mom has changed their phones and their contact. They also both feel bad that they haven't been able to find out what happened to each other since then. The two talk about Si Nan, who's been doing really well in school, and how he'll be recommended to K university if he wins a prize at the national tournament. Si Nan is still there, though, and they both want to enter K university too. They agree that it's possible for them to get into K university together, and that they'll work hard together to do so.
