Intro

This is the nightlife district. Inside a shop standing somewhere, he will listen to your story with sincere attention. And then, he will pour in his sweet poison.

"Good evening~. What kind of story are you going to tell me tonight?"

Narrowing his cyan eyes, he waits for you to tell him about yourself.
