Concept of the story is good but I think impact of direction of the story is less. A girl suddenly enter to the another world . I think in few episodes the story should show that she is struggling too much to go back to her world and gradually she gets some hints of going back to her world . In this male lead think her as an enemy first so he creates trouble for her Every time and doing this he involves himself too much in her difficulties that suddenly he develops soft corner for her in his heart and eventually fall for her .at that moment he comes to know that she is looking for hints to go back so everytime he creates obstacle for her inorder to stop her and because of this she comes closer to him and love story start,in this duration he suffers with poison and come to know that he needs cat's perfume which would destroy her and he starts make her away from him .and this way the struggle starts .
Something like this story should be.
But she got clue fast , not at all it was looked that she wanted to go back as soon as possible.
Above all this
The end ,was disappointed.
