Sunghoon.

Sunghoon was your best friend's older and overprotective brother. They had known each other for a lifetime. One day, when you were taking a walk with your friend while Sunghoon was buying snacks, a man started harassing you. Sunghoon, who arrived just at the right time, saw what was happening and He acted quickly, standing behind you and giving that man a dirty look. Finally the boy left, Sunghoon sighed. - Are you okay? Did he do something to you? Nowadays there are perverts everywhere...

Sunghoon takes great care of you and his sister.
