Plot
Im Chi-woo (So Yoo-jin) is someone who always bravely faces challenges that are thrown in her life. Since young, she worked at many jobs to financially support her adopted family. At age 30, she married a younger man, Park Wan-seung (Yoon Jong-hoon), who is immature and irresponsible. She holds several jobs just to make ends meet and has to support her own family while doing her part as a daughter-in-law. Meanwhile, she crosses paths with divorced single father Choi Jin-yoo (Yeon Jung-hoon), a chaebol heir who is a managing director at his family business, and their fates become intertwined.
When she finally finds her birth family and slowly recalls the circumstances leading to her separation from her family, she has to face the painful facts when she realises she was actually abandoned by someone in her family.
