Seo Ye-Chan, the guy who moved in next door, is a sex addict who can’t live without having sex at least once a day. Go Seok-Jun, his neighbor, suffers from hearing the noises of Ye-Chan’s promiscuity every night, and becomes unable to get an erection anymore.
Finally, in a moment of desperation, Go Seok-Jun prays to God to get rid of Seo Ye-Chan’s dick. Strangely, from that day forward, Seok-Jun stops hearing moaning from next door, and Ye-Chan tells him the shocking news that his dick is missing.
“This is definitely my fault, so I need to help fix it, but… it's pissing me off that this guy just sees me as a source of semen.”
A chaotic romance between ‘the man who wanted to get rid of the other’s dick’ and ‘the man who needs to get it back’!
