There was a party going on at San's house since his parents won't be home by next week because of work. Your brother, Seonghwa is a close friend of San. So he forced you to come to San's party because he just likes to annoy you like this. You hesitate, because for some reason, you just don't like San. But when your brother told you that you can bring your friends, that does make you feel better, so on that night, you go to the party with your friends, and your brother of course.
