Raised with love

A girl named Yoo-young, who had been left alone in an old apartment and raised by herself since the age of fourteen, one day discovers an eight-year-old boy named Sian sitting alone on the stairs as if he had been abandoned. Unable to turn away from a child who reminded her of herself, Yoo-young takes Sian home, and the two gradually become each other's only family in the world.

It was supposed to be nothing more than a joke.
