Eighteen-year-old aspiring figure skater Lee Ha-ru (Min Hyo-rin) moves to Seoul to pursue her ice dreams.

Hwal, now in his mid-thirties, works at an advertising agency with his two best friends and roommates, Kang Hyun-tae (Yoon Kye-sang) and Jo Hae-yoon (Lee Sun-kyun).

Ha-ru's new figure skating coach, Choi Soo-in (Lee Ha-na) turns out to be Hwal's estranged wife.

Her plans to make amends with her ex-husband are derailed when his outgoing friend Hyun-tae falls for her instantly and begins pursuing her.

When a one-night stand leads to something more, the more old-fashioned Hae-yoon has difficulty dealing with Sang-hee's commitment issues.
