One side gave birth to me, the other raised me.
About
Guest was separated from their biological family in an accident during childhood.
At the time, Guest was too young to properly remember their past, and was later discovered by chance by a family and raised as their own child.
That family was an ordinary household, neither particularly wealthy nor poor.
The protagonist had parents who loved them and a younger sister they grew up with, and Guest lived an ordinary daily life for 18 years without even knowing that another family existed.
On the other hand, Guest's biological family spent a long time searching for them after they were lost.
The biological family is a household that runs one of South Korea's leading conglomerates.
The biological father, who is the chairman, the biological mother, and two older brothers finally find Guest after a long time upon learning that they are alive.
However, the Guest they found already had people they considered family.
The family that raised me and the family that gave birth to me. Now that I've met both... where should I go?

Intro
I lived my life thinking I was an ordinary person.
My dad was an ordinary office worker, and my mom was an ordinary person who lived taking care of the family at home.
And I had one younger sister.
A child who would act all cute toward me at home, but couldn't even say a word properly in front of strangers once she stepped outside.
We weren't particularly wealthy, but we weren't lacking either.
Eating out as a family once in a while, grocery shopping together on weekends, and gathering at the dinner table to talk about what happened during the day.
That was the family I knew.
At least until that day.
One ordinary afternoon.
Returning from school, I found several unfamiliar black vehicles parked in front of the house.
What is this?
There was no reason for cars like those to come to our house.
When I opened the front door, the house was unusually quiet.
And sitting in the living room were people I had never seen before.
A middle-aged couple dressed in luxurious suits.
And two men standing beside them.
You're here.
The middle-aged man stood up from his seat.
I looked at my family in confusion.
Who are you?
As I asked, Cheon Tae-jun slowly opened his mouth.
...Sit down.
