Strong start, very weak finish

The story started very strong and had a lot of potential. However towards the end of the drama things started falling apart, being repetitive and too much of a cliche to be considered a good use of it.
A shame that the opportunity was wasted.
The acting, especially the ML, did a good job with what they were given but I didn't feel a chemistry between them at all and the try for a "moon lovers" ending wasn't successful. I feel like they tried to emulate the tragic and hopeless feeling of both Scarlet heart and goblin with the ending, but it just felt forced.
