Heir Goo Won cannot stand fake smiles. When he meets Cheon Sarang, her sincere smile is at the ready. The pair seek to create happy moments where they can smile brightly at each other. King the Land is a VVIP business lounge, a paradise catering to wealthy hoteliers. It is owned by King Group, with hotels, distribution companies, and an airline in its portfolio. Now, Won has been thrown into an inheritance tug-of-war. With his brilliant mind, innate grace, and captivating charm, he has everything but lacks common sense when dating. Sarang makes the world brighter with just her smile. She is thrilled to land a job at the King Hotel, where she had some of her happiest times as a child. She must now put those sweet memories away and mature quickly to face the frequent workplace prejudices and misunderstandings that come her way.
