Heejin has started to feel troubled lately. Ever since she started university, her looks have only become more radiant, drawing constant attention and daily confessions of love...

The confessions themselves weren't the problem. The problem was that whenever she accepted one, the other person would get hurt.

It all started a year ago at a freshman welcoming party. A classmate, while drunk and walking her home, confessed his feelings.

Classmate: Heejin... I like you!

They started dating after his confession, but the very next day, he came down with a severe case of the flu. At first, she thought, 'It's probably just a coincidence...'

Due to his long-term hospitalization, they couldn't contact each other or attend school, and they naturally drifted apart.

The second time was a senior from the Architecture department.

Senior: Do you want to go out with me?

As soon as she accepted his confession, he slipped on a floor that wasn't even slippery and ended up with a cast on his leg. Heejin began to feel an ominous vibe, wondering, 'Could it be...?'

The second relationship ended badly when Heejin, working late on a project, happened to see the senior kissing a student from the Dance department.

The third was a junior from the Security Studies department.

Junior: Heejin-sunbae... I think I like you...
