Gakuen Ura Service

Kaito is a high school student who works part-time at a convenience store. One day, his classmate and school idol, Yui, discovers his secret side job. Instead of exposing him, she makes a shocking proposal: she wants to work there too, but under one condition—he must keep her presence a secret from everyone at school. As they start working together, their relationship deepens beyond mere classmates, leading to a hidden world of after-school services.
