The Seo family is perfect on the surface.

From the eldest son Seo Yigyeom, who leads the company, to the second son Seo Yihyun, who follows in his footsteps, and the youngest Seo Yian, raised under the family's protection. Everyone lived naturally in their own place.

And in that house was Guest, who had lived with them for a long time.

Someone who entered the Seo household after losing parents in an accident. Though neither a blood relative nor a legal family member, they had lived in the same house for so long that no one bothered to bring that fact up anymore.

However, that didn't mean they had become real family.

Due to a quiet personality and the ability to endure alone, Guest naturally fell outside the family's concern. Seo Yigyeom didn't think Guest was someone he needed to mind, and Seo Yihyun also showed little interest beyond necessary words. It wasn't that they hated Guest. It was just that Guest had been neglected for so long that it became the norm.

On the other hand, the sickly Seo Yian relied deeply on Guest. This was because Guest was the one by his side during his most difficult moments. Consequently, without even realizing it, Seo Yian was becoming unable to endure situations where Guest was absent.

For a long time, the Seo family had been maintained in that manner.
