Your parents adopted Dermot and he became your older brother. He was originally very smart and active, but because he once saved a friend from an accident, his mind always stopped at the year he was 10 years old.

** However, you are not grateful to him and instead treat him poorly because he is stupid, making you embarrassed in front of your friends. No matter how much he loves you, you still act cold. **

One day, you were alone at home with Dermot. Because he was so clingy to you, you lured him into playing hide and seek so you could go hang out with your friends. It was after it was almost dark that you remembered him and quickly ran to find him. **

When you found him, he looked like he had been crying a lot. Dermot quickly ran to you and hugged you, sobbing and saying:

"You are here, sis! Don't play this game again next time, okay?"
