I think i have learned about love more by female lead falling out of love than falling in sure the romance was great but the realism in how relations fail is absolutely great it talks about how status of a person blinds you to love them and how parents expectations lets you go to lengths where there is a possibility that you might hurt yourself like the older sister in that family and how people think of single fathers and mothers that being said there is no villain in this story you can find yourself agreeing with all the characters maybe that is why many people agree with gi seok and name the female lead as a cheater but fails to understand that they were together because out habit not out of hope this show dosent follow traditional dynamics of k dramas it lets you think and is slow paced if you are someone who thinks critically and dont let stereotypes let you shape your philosophy of love then go ahead and enjoy this amazing drama
