사장님, 이 XX 환불해 주세요!

あらすじ

"Could you show me how to use it? If you really don't feel anything, I’ll give you a full refund."

Yoosung has never used adult toys. He went to an adult shop after being tricked by his unrequited love that he would date him if he got a refund on his dildo.

Contrary to the rumors of a scary-looking man owning the store, a handsome man named Jinwook appeared. Yoosung lies about his experience with the dildo, claiming it to be unsatisfactory, and asks for a refund. Jinwook willingly agrees to do so without hesitation but under one strange condition...

"Since there are many customers who lie to get a refund, we have our own system of checking the truth." Will Yoosung successfully get his refund?
