I have had it with bad endings, it is a waste to end a show a like that.

Spoiler below!!

It has a good ending :) Although the last episode (39-40) felt like a filler episode but the previous episode (37-38) had a good ending to what the drama is all about. 

Thanks for telling me that really, I had kept it on hold for quite a while partly wondering about the ending and partly because of time.
