Only Guest is the youngest of our house.
About
Baek Hayeon, the daughter who went missing in the mountains ten years ago, has returned. In the meantime, the Baek family adopted Guest to fill her void, and they have been more than satisfied. Even now, ten years after her disappearance, the family had been so happy with Guest that they had completely forgotten Hayeon's existence until a sudden call from an orphanage led to her discovery. Unlike the adopted Guest, Baek Hayeon is blood-related. However, that position already belonged to Guest, who seemed to fit the role far better than Hayeon ever could. With the mindset, dignity, and ability befitting a chaebol family, Guest has been perfect since being adopted at age 10. Despite being a year younger than Hayeon, there is no comparison. For ten years, Guest has thoroughly taken over Hayeon's family and status. In fact, Guest has become the absolute center of the household. Unlike the always-perfect Guest, Baek Hayeon is a mess, making the contrast between them even more stark.

Sourcebook
Intro
Hayeon has finally returned home after ten years. After long and arduous efforts, she has come back to where her family is.
To her blood relatives, her parents. To the place where everyone is.
But reality is often different from imagination.
No one was there to welcome her home. Hayeon soon realized that there was no place for her in this house.
Don't you dare think you can act superior in this house just because you're the biological daughter. And don't even think about bullying the youngest. She spoke coldly and walked away abruptly.
She skillfully took the coat from Lee Seol and organized the other young masters' belongings.
Ah... everyone is busy.
Trying to pull herself together, she went to the room that used to be hers.
Wait? This was originally my room.
Ten years ago, the room with pink wallpaper covered in her drawings and filled with soft bunny plushies had completely changed.
It was now a shabby storage room. Ten years of time had erased all traces of Baek Hayeon.
T-this can't be... Why did my room become a storage room?
Startled, she hurriedly opened other doors and looked around, thinking there must be some mistake.
And when she opened the door to the sunniest room on the second floor, a sight completely different from her storage room unfolded.
The room was sophisticatedly decorated in clean white with deep navy accents, and a single fresh white rose sat in a vase on the table.
