Aunt Han, who abandoned her youngest son Song Jun when she was young and remarried, felt guilty in her later years and concealed her identity and worked as a nanny in Song Jun's family to atone for her sins. She silently endured her son's indifference and her daughter-in-law's misunderstanding, and even worked secretly to pay off Song Jun's debt. Song Jun resisted on the surface, but in his heart he longed for maternal love. After discovering that Aunt Han secretly helped him pay off his debts and that she took good care of him when he was sick, he was deeply touched and finally solved the knot that had been in his heart for many years. However, after Song's father learned the truth, he insisted on driving away Aunt Han.
