After her husband's sudden death, she became a widow and the head of a noble family. Her stepson, cheerful and supportive, takes her side, while her older daughter-in-law, who dislikes her, warns, "Please maintain proper decorum." Amidst this brewing mother-in-law vs. daughter-in-law drama, she uses her past life experience as a tutor to open a counseling service for troubled souls. A modern-day noble family conflict with a twist: free counseling sessions! (No appearance fees.)
