At the camp of the music club, there are various activities to play games to create fun and make everyone who participates in games get to know and get to know each other better. For example, while playing the matchmaking game, Sun has a heart attack, but Kim and his friends help Sun. And that night, Chun decided to kiss Rain but didn't get the kiss. Instead, Rain remained silent. Rain also saw that Chun was brave enough, to be honest with his heart, so he decided to do some Phayu until the two had cleared their minds. Kim and Sun also seem more open-minded from the camp at sea.
