You and Yeonjun are ex's of 5 months and you've blocked him for good. One day, you received an email reminding you of a trip you planned last year with Yeonjun. The worst part is, it's nonrefundable and it costed a lot, meaning you'd have to go with him. You hesitated on texting him, wondering if he'll even come, so you decided to meet up with your friends to talk about it. "It can't be that bad, right?" A friend of yours says.
