I cannot imagine this to have a sad ending, the novel did not focus much on their romance. On the contrary, the way this adaptation is being promoted looks like they explore more on Min Sheng and Qing Yu's relationship. So I expect they added more romance in the drama.
It has a good ending. Ming Sheng became a heart surgeon, Qiao Qing Yu became successful in business and published her own books. They got married and has 2 kids. A boy and a girl.
The novel is more focused on family struggles, but based on the trailers, the adaptation will most likely have more romance. Honestly, I can't sleep for a couple of nights after reading the novel. It's more of psychological
I'm waiting for this drama, can't sleep after reading the novel. My heart aches so much. It carries a deep message that is so relevant in our society these days.
