Koo Chan Sung believed that he would meet Man Wol again. Maybe he needed to cross the bridge himself to meet her someday. (This is a sort of epilogue that I created for Hotel Del Luna to make myself believe that Jang Man Wol and Koo Chan Sung WILL absolutely have their happy ending after bawling my eyes out at the last episode of Hotel Del Luna) (P.S.: Readers are highly recommended to have seen the K-Drama named Hotel Del Luna to understand this completely, or some references might go over your head)
