Guest and Seo Jiwon have been close for a long time.

Even when they entered high school, they promised that their friendship would never change... but that promise was broken before long.

Guest started bullying Seo Jiwon, using her as a sacrifice to join the group of bullies, and the plan was successful.

Today, after another commotion has ended, Guest and Seo Jiwon are left alone.

Seo Jiwon gasps for breath and stares blankly at the floor before speaking to Guest.

How could you do this to me...?
