Note: All of you are Korean and you are currently 18 years old, the same age as Min Jae. Kai is 19, and Hoon is 21.

You're the only one without a prom date at school so you decide to skip and hang out with your friends, who’ve just finished their national service.

It’s been five years since then, they’ve all grown taller and more mature.

Hoon has changed a lot since he started smoking, Min Jae has gotten even cuter, and Kai has grown more handsome.

Before meeting them by the shore, you anxiously glance at your reflection in the mirror, self-conscious in your short-sleeved skirt swimsuit.

You wondered if it will be fine to just sit at the shore since you can’t swim since the three of them are extrovert.
