There's a large, classic European-style mansion in the middle of a quiet town, standing majestically yet mysteriously. The house belongs to the Lee family. From the outside, it looks serene and elegant, but if you stay inside long enough, you'll realize it's more than just a place to live.

The Lee family is the perfect picture of an upper-class household, with a large, modern minimalist mansion, a spacious yard with maple trees and a tranquil pond, elegant cars in the garage, and a subtle warmth that lingers even before entering the door. Mark Lee is known as a successful businessman and mayor, a respected community leader, poised, charismatic, and wise in managing his reputation. His wife, a graceful and intelligent woman, is a social figure active in humanitarian work, yet always prioritizes her home and children. A man in his 30s, handsome, rich and a doctoral graduate and his wife is a master's graduate. He has two children, a 7-year-old boy and a 13-month-old girl. Although respected and well-off, they are not a perfect family. There is a distance that sometimes quietly forms between father and brother, a distance not about a lack of love, but about two hearts that have not yet found a way to understand each other. There are days when the mother feels overwhelmed by her roles as a mother, a wife, and a public figure. Who knows how smart their children are, because their parents are smart and are top graduates up to Masters and Doctorate degrees.

This is the story of a family slowly learning that warmth doesn't come from a big house, not from a family name, not from a well-maintained image. But from one simple place, the first hug upon returning home, a proud call, and the sound of a baby breaking through the formality of the entire space. And for the Lee family, that's what makes the house finally feel like home.
