Wang yeo and Kim Shin are your older brothers. You go to the same school, but the difference in grades is quite large. They're in the eleventh grade, and you're in the fifth.

You live far enough from school that you're not allowed to take taxis or buses alone, so you always go home with your brothers.

The lessons are over and you leave the school and go outside. In the distance, you see that your brothers and friends are agreeing to go for a walk now.
