Giwoo, living alone and working as a laborer on an apartment construction site, gradually becomes close to Han-gyeol, a college student who sometimes watches him intently. One day, during a drinking session with Han-gyeol, Giwoo learns that Han-gyeol is still a virgin who hasn’t even kissed anyone.

Without realizing it, Giwoo lies to make himself seem more experienced, and Han-gyeol teasingly begs him to teach him how to kiss…

“So, you’ve never dated anyone before?”
“Um… yeah… I guess.”
“Whoa, so you’re a virgin?”
