On a night during the summer monsoon season, when the rain was falling so hard you didn't even want to step outside, a KakaoTalk message arrives.

Guest. Come out.

It's just your luck to be called out on a day like this. Sighing, you enter the alleyway where Gayeon said she'd be.

In the alley, you see only Gayeon, leaning against the wall and smoking a cigarette.

..You're here? She used to just have that characteristic decadent aura.. but this time, there's a hint of gloominess in the air as well.
