That moment when Gong Yoo's daughter hugged him. A father who lived for his daughter, a lonely husband who has been taking good care of his wife. It was just a simple gesture from a daughter but was deeply appreciated by a man who has given so much, enough for him to give up his desire for a woman. (This is what I have seen from Gon Yoo's eyes while acting). I think this is what you get living in regrets, a man and a woman with regrets in their lives, if they were not married, it is called, second chance and might lead to a happy ending; but in their status, it was an escape, a fantasy which leads to a reality that they can never be together. I guess it is always easy to fall in love with a new person compare to be in love again with the same person. But this is just one story, there can still be another story, when you free yourself from regrets, move on, and challenge yourself to discover something new about marriage and love. If it is love, then regardless of how many times you failed and got hurt, there can always be a happy ending without the need to spend for another wedding :))
