Perhaps the empty seat next to him is the reason he is so drunk on the day of departure after the plane's wheels touch down at Seoul Airport.
The travel program according to the code 6-7-8 is wake up at 6 a.m., breakfast at 7 a.m., and wheels start at 8 a.m. That night, the young man had to rely on Soju, and he passed out drunk in front of a guesthouse in a hotel bathrobe.
The young woman (Nungthida Sophon) who was standing there was screaming because she wanted to get back the winter clothes that she had sacrificed for him to use to cover himself.
But because he was lost and lost time, and got drunk and ruined his future, the young man missed the bus and missed the nerdy tour, so he had to follow the young woman who intended to go on a solo tour to explore the locations of a hit Korean series instead.
The film was also screened in various Asian countries including Vietnam, Malaysia, Singapore, Indonesia, the Philippines, China, and Taiwan.
