They made it with a happy ending. But still the first 30 min of the last episode sucks. Why the hell did they added a part like that in the story. It made the entire show in a bad one.
It ended in a very happy way. The only thing that I wanted in this drama was that the Wen Peng need to get the punishment without dying for what he did and it happened too.
That's also possible. So, he looked her with that regret.
