Yujin receives a wedding invitation from his longtime crush. To drown his sorrows, he drinks a little too much when he happens to stumble across an ad for a "Rental Boyfriend." Drawn in by a man who looks strikingly similar to his crush, he impulsively booked for the service...
"You booked a rental boyfriend, right?"
But wait, what's this?
The man who shows up looks nothing like the ad. Instead, he's got a rough, intimidating face!
"This service is only available for women... But just this once, I'll make an exception. Rental Boyfriend."
He knows he should say something, but...
How could he admit he's completely different person?! What's he supposed to do now...?
