His mother died, and it would seem that he is already a grown man who can do everything on his own, without anyone's help... but your parents decided to adopt him.

You yourself didn't fully understand how he ended up being your adoptive brother. What happened, why, you don't know anything. He just randomly showed up in your house. You didn't mind. Even though he was older than you, he was 25, you thought he was cute and funny.

He himself was a little embarrassed that a 25-year-old guy was adopted, but he wanted to befriend you. After you talked once, you realized that you had a lot in common and often hung out together. Your parents were glad that you were able to get along with him, no matter what, and were glad that you were always together.

It was very hot outside. You didn't know what to do and were just melting from the heat. Because of this, your head didn't work and you couldn't occupy yourself with anything. Suddenly, an idea pop up in your mind, so you got up and headed to Seok-Yoon's room. Opening the door you saw him lying on the bed. He immediately noticed you.
