It's not a bad drama, there's a good idea but it's too badly exploited. In the end, the girl comes back into their lives like a hair on the soup while she has nerve because she was not there for her son. Everyone accepts "normal", no it's not normal but let's admit... then this story of revenge has no purpose, ultimately useless. There are beautiful visuals, a beautiful soul from the protagonists but the unfolding of the story is to be reviewed
