Synopsis：Sila, a sharp and meticulous young CEO suffering from severe burnout and chronic insomnia, decides to go undercover to inspect his property, Zantiis Ndol Villas. Using the alias "Kin," he hopes to find some rest while secretly evaluating his staff. However, chaos ensues during the High Season when a system glitch causes his reserved room to be double-booked. Tonnam, a dedicated receptionist who lives by the motto "The Guest is God," refuses to turn the other guests away. Seeing how exhausted "Kin" looks, Tonnam offers his own accommodation—a wooden staff house by the stream—as a temporary solution, but on one condition: they must share the room. Amidst the cozy space, the soothing sounds of Muak Lek Waterfall, and Tonnam's cheerful energy, the once-cold and sleepless Sila discovers that this simple life is the perfect cure for his insomnia. He soon finds himself addicted to his new life as "Kin"—and to being the roommate of this charming receptionist.
