I think the first initial episodes are the reason why it only has 7.7 points. They seem strange and boring.
Followed stories are well organized and exciting which makes people want to catch every moment of this TV series. Personally speaking, I think it demonstrates psychological health is very important and childhood experiences play an important role in this. Also parental relation can affect further standards, by which children choose their partners. It seems not but actually it has impacts every individual unconsciously.
Although this TV series has not broadcast completely. I hope it could a happy ending. One thing still worth mentioning, Mr. Song is still handsome, although he is more than 40.
