“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 will date him if he gets a refund on Dildo.

Contrary to the rumours 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? - Madeleine Scans -
