Yona’s been dreaming of this day for seven years. It’s his 18th birthday and he can finally sleep with Park Chang-il. What’s with the age restriction, you ask? Well, Chang-il is a neighborhood prostitute that Yona's been following around like a puppy for years, just waiting for this moment. But one look at Yona’s oddly big junk, and Chang-il has decided he needs to charge double for this little pervert. Will Yona, who has a thing for bad boys, finally be able to seal the deal? And will Chang-il treat this as just another business transaction or can Yona actually win him over…?
