Chairman Lee Kang-hyun, who leads the Lee Group, the nation's largest conglomerate, and his family. Possessing immense wealth and power, they are known to the public as a successful chaebol family and a harmonious, prestigious household. They are evaluated as a family with both excellent business acumen and sweet familial love, often becoming the object of envy everywhere.
The grand mansion in downtown Seoul where the family lives together is large and luxurious, befitting its reputation. It is equipped with a large garden, private studies, indoor sports facilities, and a swimming pool, with butlers and managers residing there to manage overall life. While their individual living spaces are strictly separated, the family members spend time together as a family by having meals or attending important events despite their busy schedules.
However, the appearance inside the mansion is not as perfect as what is known to the public. In particular, there was a clear difference in the family's attitude toward the youngest twins, Sian and Guest.
The family's interest and affection always headed toward Sian first. With looks resembling his mother and excellence in both studies and sports, Sian naturally monopolized the family's love. On the other hand, Guest was always an afterthought despite being a twin born on the same day. In family conversations, Sian's stories came first, and even when Guest wanted to ask for something or receive attention, they could not easily make it into the priority list.
It wasn't that the family hated Guest or intended to hurt them. It was just that taking care of Sian first had become so familiar, and they simply failed to properly look back at the disappointment and loneliness Guest must have felt in the process. The family members weren't even consciously aware of how differently they were treating the two children.
In that way, things that no one thought were a problem piled up over a long time. On the surface, the Lee family remains peaceful and harmonious. However, no one yet knows how much regret the small choices the family took for granted will one day return as.

The mansion had been busy since morning. Today was the twentieth birthday of the Lee family's youngest twins, Sian and Guest.
In the spacious hall, colorful decorations, food for guests, and a large cake were being prepared. The family members were also gathered in the living room, checking the party preparations.
What about the gift?
Lee Kang-hyun sat on the sofa, putting down his documents as he looked at Lee Do-yoon. At the short and concise question, Lee Do-yoon checked a luxurious gift box placed next to him before answering.
Yes. I prepared what Sian wanted.
As Lee Do-yoon placed the gift box on the table, Lee Seo-jun leaned his arm against the back of the sofa and chuckled.
As expected of you, Hyeong. Sian is lucky.
At Lee Seo-jun's words, Lee Sian smiled awkwardly and scratched the back of his head. Lee Do-yoon placed the box on the table without much reaction.
You guys all prepared it together. Thank you.
Lee Sian looked at his older brothers in turn and smiled brightly. Lee Kang-hyun also looked at the youngest for a moment and nodded as if satisfied.
It wasn't that the family didn't know today was also Guest's birthday. However, when choosing gifts and preparing for the party, their interest naturally headed toward Sian first.
