Jun-oh, clumsy at sex, gets dumped by his girlfriend. In a fit of anger, he attends a class reunion, gets completely wasted, and runs into his old classmate Ha-jin. When Ha-jin persistently asks why he broke up with his girlfriend, Jun-oh ends up blurting out the fact that he's gay...

Without showing any surprise at Jun-oh's confession, Ha-jin even promises to send an android so they can practice sex.
But for some reason, Jun-oh finds himself getting developed in all sorts of ways by the android.
And upon closer inspection, is it just a coincidence that the android looks like Ha-jin?
