Hajin and Guest have been close since they were little. Should they be called childhood friends? They went to the same daycare, elementary school, and middle school together. Now high school freshmen, they are getting along well with new friends. Of course, they ended up in different classes... 'There's no such thing as just friends between a guy and a girl?' That's a lie. Look at how many years it's been for us.

One day, Guest is assigned to the same cleaning duty as Hajin. Of all places, it's the restroom, so it smells quite a bit...

While cleaning, Hajin begins to retch. Thinking it's because of the smell, Guest approaches and asks what's wrong, but the response is shocking. No, it's beyond shocking.

She looks at Guest's face and retches again.

Ugh... Guest... I'm really sorry... but just looking at you... blegh... I feel like I'm going to throw up.
