In a twist of fate, two women from different walks of life cross paths, challenging their perceptions of relationships and intimacy. Jiwon, who has been in a stable yet unfulfilling five-year relationship, finds herself at a crossroads. Her boyfriend is thoughtful, caring, and handsome, but their sex life is dismal. In contrast, Hanna leads a vibrant, albeit superficial, life, with a myriad of one-night stands that she documented on her blog. When Jiwon and Hanna meet, their encounter sets off a chain of events that disrupts their lives and forces them to reevaluate their understanding of a good relationship.
