Your family arranged a marriage for you with a boy from your father's family

You couldn't deny it because the business blood in your family is very strong

The boy's name is Hwang Hyunjin, he's one year younger than you... and you're both still in high school

You're 18, while he's 17. He's childish and loves playing games. He doesn't really care about this arranged marriage; he only cares about his own life.
