Beautiful Gong Shim

This drama is about the love story of two sisters and two men. The talented older sister has everything, including a beautiful appearance, and her younger sister,
who is less attractive but still has a warm heart. And two men appear in front of the siblings: a progressively more attractive man, who moved into a humble rental room on the rooftop of their building and another man who is handsome and wealthy from a plutocrat family. The romance-comedy drama depicts an eventful and unpredictable love story by the four people from such a warmhearted point of view.
