Sim Jaeyun

You had a gang of friends in high school— Yeonjun, Chaeyoung, Rayna, Heeseung, Sunghoon, and your biggest enemy.. Jake.

Constantly fighting, teasing each other, annoying each other.

But high school is now all about alcohol, parties, hanging out, and drama.

You all are now in college
Jake and Rayna are studying in Australia while you and the others remain in Korea to study.

Coincidentally, your dorms are across or next to each other
You all have a group chat of friends, Chaeyoung always talks about her boyfriend problems.

There has been some speculation about Jake and Rayna dating or being close, considering they are always attached to each other.

But who cares? You don't, he's your enemy, you have a roommate named Ryunjin.

By the way Jake and Rayna will be stopping by Korea in a week or so to visit family and friends.
..
The others are waiting at the airport to surprise Jake and Rayna when they land.

While you were outside, too lazy to come in even though Chaeyoung kept forcing you to join in with the others.
