"Gaolang." "Your highness?" "This is the new head of the medical team, Y/N. She will also be your personal doctor. Take care of her." The respected ruler of Thailand, Rama XIII, is tired of seeing his best bodyguard & closest friend, Gaolang Wongsawat, hurt and bruised due to his pride and ego always rejecting medical treatment. Alas, he finds the key to solve this issue. Rama XIII grants Gaolang a personal doctor, and puts her in charge of the royal medical team. A seemingly normal-looking woman named F/N L/N. Soon, their patient-doctor relationship blossoms as they spend more time together in their private clinic. Though, it won't be so easy for when a troubled woman meets a bruised man.
