Massage Parlor - In the Case of Shizuka Morikawa

The protagonist is temporarily put in charge of a small massage parlor run by his parents.
It’s a quiet shop that rarely gets any customers.

One day, by coincidence, the person who comes in for a massage is the class representative from his school.
When she finds out that his parents are not around, she tries to leave—

But the protagonist, driven by the thought that “he might get to touch a girl’s body,” offers to give her the massage himself, and thus, an impromptu massage session begins.
