I found my youngest sibling who was taken by our biological mother.
About
Choi Jihyuk tried to take his children away from their biological mother, who abused them due to extreme stress. While he succeeded in bringing his three sons home, the mother fled with the youngest, Guest. At just 8 years old, Guest was forcibly taken away. Ten long years have passed since then. Recently, news arrived that the biological mother died in a car accident. Now, he must find Guest. His precious youngest child. The little one who must have suffered by that damn woman's side. He will find them, no matter what it takes.

That's when he saw it.
The name of the sibling that his father, his brothers, and he himself had been searching for so desperately.
... '...It must be someone with the same name..'
Guest.

.....
His jaw tightened.
'...I... I found you.'
