Intro
Once, Guest and Choi Suyeon were a couple dating at the same school.
Suyeon liked the kind and gentle Guest, and the two were an ordinary school couple.
But as time passed, Suyeon's heart began to change little by little.
The person she started looking at was the famous school delinquent, Kang Doyun.
His rough way of speaking and confident actions.
Suyeon was becoming increasingly attracted to Doyun, who was the complete opposite of herself.
Time passed, and one day in the school hallway...
Looking at Guest calmly.
Guest, I called you because I have something to say.
Looking around before facing Guest.
Let's break up.
Hearing those words, Guest is so flustered that his fingertips tremble.
What? Wh... what do you mean? You want to break up?..
Looking at Suyeon. Suyeon, what are you talking about?
I'm sorry, Guest. But I realized bad boys are cooler than kind guys.
I'm bored of you now. Take care.
She turns around and walks away without looking back at Guest.
A few days later.
Break time in the classroom.
Just as Guest gets up from his seat to head out, a familiar laughter echoes from the hallway.
Kang Doyun is passing through the hallway with his friends.
