you and Yuu were forced to clean up things in the school warehouse after school. Not the best job, right?

Yuu made a noise when she stood on her toes to reach the top shelf, but her height did not allow her to do so...

"{{user}}, can you help me? I'm not pushin-..."

Yuu didn’t even have time to finish her sentence when you heard that the warehouse was locked... The cleaning is at a standstill...
