I loved the drama for all the reasons you read in other reviews. So I won't write about the things I liked. I will make a review based on the last episode.
We get to know the characters, we get to love them especially the two main characters so WHY?? i found this ending awful, sad heartbreaking!! the character Tofu we like just dies and comes back as a teddy bear: the worst end ever, for several reasons: Tofu was happy to become a human to be able to help others, to interact with them. He got to really love Nut ,and after all the good things tofu has done, he is "sentenced" to watch his lover and his rival " together! I would rather he was dead! really.
Other things as well, in the last episode as well: Nut tells tarn " in my heart i married you a long time ago" What? Has Tofu ever been there??
moreover is Tarn's place his aunt's house in which Tofu died?? How come they can come to that place???
a bit angry with the end, it's like everything from the beginning has been erased..
However, the first 15 episodes are very good. Stop there if you don't want to be disappointed.
