This is the worst mother-daughter relationship ever written. The writer is completely clueless on how to write relationships. The same goes for the father-daughter and other relationship dynamics in the drama. In fact, writing in general was awful. The story itself was too thin with little to no content. No one met the father in person until episode 11 which they had to because they needed to stretch it. It deserves even a lower rating. The writer couldn't even write a generic ending. It was meant to be focused on the mother daughter dynamic but the mother decided to die alone with her doctor friend. Not with her daughter or the ex-husband or the boyfriend. They never told the daughter about her illness until she found out suddenly that her mother died. All what the daughter got was a generic email 1 year later after her mother's death. Shitty ending with no climax, you would expect at the very least some good one final good bye dialogue between the mother and her daughter.
