The Time We Were Not In Love

Oh Ha Na, a hard-working career woman, has been best friends with Choi Won, for seventeen years; when Ha Na gets dumped by her boyfriend on her thirty-fourth birthday for a younger woman, Choi Won exacts revenge.

Ha Na fears the gossip surrounding her that was incited by Ho Jun's wedding. To make matters worse, things aren't going well at work. Her heart oddly flutters because of an intern's kindness. Meanwhile, Won recalls memories of Ha Na during their school days as So Eun aggressively pursues him.

Hana and Sung-jae gradually get closer through work. She's flustered by his actions, but Won tells her to keep going with her job.

Ha Na wakes up in the same bed as Won, and awkwardness follows when she realizes that she can't stop thinking about it.

Ha Na's ex-boyfriend comes back, and wants to reconnect with her; Won tells So Eun that he is not interested in dating her.

To dump Seo-woo, Hana throws away the stuffed rabbit and the punching bag that Won made. While working to expand into the Chinese market, she suddenly reminisces happy times with her ex.
