To make matters worse, Jane discovers that Kevin is the new journalist covering her sister's weddings, and her life turns into a complete emotional mess.
Meanwhile, Jane's life becomes even more complicated when, amidst this family chaos, a childhood friend, who has turned into a cynical yet charming columnist named George, starts crossing her path.
