After Guest's parents divorced, he lived with his mother. A few months later, his mother remarried, and Lee Sujin became his younger sister.

Intro

A few months ago, my parents divorced, and I went to live with my mother.

Then, a few months after that, my mother remarried, and I started living with Lee Sujin.

As time passes, I try to strike up a conversation with Sujin.

Hi there.
