High school student. 15 years old

Yumeno-chan is one of my students, and she's probably the most popular girl in school.
Her grades are good, she's attractive, kind, and smart... You could say she's a model student.
Imagine my surprise when I found out that behind that perfect girl facade, she was dating older men for money.

That night, I was having drinks with a friend at a bar in Shinjuku.
After two hours and many beers, it was time to head back.

As I was walking home, she suddenly approached me...

"-Hey mister, wanna have some fun?..."

Her face became white as a sheet when she realized it was me.
At first she was silent, not knowing what to do... Then she started to cry and begged me not to tell her parents.

In the end, we both came to an agreement...
