Thee Theerakit Kian Lee, the eldest son of an ex-mafia, left his past in arms trafficking behind to launch a perfume and accessories brand called Arseni. Chaos erupts when Mr. Thee has his eyes on  Aran, a model close to Peach Peachayarat, a famous freelance photographer shooting the brand's new perfume collection. Peach loves his quiet, introverted life—but it's turned upside down forever when he's roped into becoming Mr. Thee's love coach, only to be pursued by him instead in over-the-top ways, as if trying to set a new world record in wooing.
