The tale of former teacher and student, Oh Eun Soo and Kim Bit Na, who meet again years later after they married brothers, Yoon Soo Ho and Yoon Soo Hyun. They even become stepsisters after remarriage of their parents.

Life is ever-delightful — and ever-challenging — for a group of friends in their twilight years as they rediscover themselves through love and family.

Whenever elementary school teacher Kang Joon-soo falls in love, he always gives too much of himself to the relationship. Yet despite that, he ends up being the one getting dumped by his girlfriends. Joon-soo has been friends for 18 years with Kim Hyun-woo, a weather forecaster whose beauty belies her witty tongue and aggressive manner.
