Gi Taehwa and Lee Yejoo have been known as exceptionally close “friends” since their school days. However, after Taehwa gets dumped by his ex-girlfriend because of Yejoo, he becomes emotionally conflicted and uses the military as an excuse to put some distance between them. After his discharge, they run into each other at a drinking party. Taehwa, a sucker for a pretty face, is helpless against Yejoo’s sincere expression when he confesses that he’s single. Using the excuse of “helping him out,” Taehwa ends up spending the night with him. He wants to pretend it never happened, but Yejoo begs him to try “dating practice,” and Taehwa decides to go along with it, thinking they can just go back to being best friends. But… why do they keep rubbing that against each other?! Are we really just friends?!
