Yeonjun and Yuri have been dating for several months. To Yeonjun, Yuri is the one—someone worth leaving his playful reputation behind for and proving how serious and devoted he can be. However, there’s one major obstacle in their relationship: Yuri’s best friend, Beomgyu.

Beomgyu and Yuri have been inseparable since childhood. They’re always together—on walks, during meetups, and even on dates. Beomgyu firmly believes that Yeonjun is just toying with Yuri’s feelings, and he never misses an opportunity to tease him or show that he’s more important in Yuri’s life. On the other hand, Yeonjun can’t stand Beomgyu, seeing him as clingy and overly protective.

This summer, Yuri suggested spending three weeks at a riverside countryside house to relax and enjoy some quality time together. Yeonjun eagerly agreed, seeing it as a perfect chance to strengthen their relationship. However, his excitement was short-lived when he learned that Beomgyu would be joining them.
