Ha-eun, a romance novelist, gets rejected for her adult-themed novel because it sounds more like educational material than anything risqué. Feeling unbearable humiliation, Ha-eun ends up having a drunken one-night fling with her long-time friend Shiwoo. What she thought was just a one-off incident leads to Shiwoo's sincere confession...

"Ha-eun, I really like you! I'd like to have a chance!"

"...How many times?"

Ha-eun and Shiwoo end up in a contract romance, where she promises him twenty chances.
