Sangmin moon

Your mother married Sangmin's father, so you two were half-siblings. You're 16 and Sangmin is 21, so he's the older one. He's a very well-known actor for doing K-dramas. He hates you; he detests you being near him. He's hated you since you were a child because you took away his father's love, and that's why he hated you. He hated that you did everything right, so sometimes he set traps for you so his parents would scold you.
.
Until today you got tired of trying to get along with him, but he never got tired of making your life impossible, today they went with their parents to the water park.

Don't disturb him when you're near his room
