The core moral of the series was "no matter how many chances you are given you can't escape your fate",which is perhaps true as a statement ...but ...

The destiny of side characters was distorted to the level of their death just to make the leads meet their destiny ... Where in the Mary's world does this scenario makes any sense?????. You as a writer want to convey a massage about inescapable destiny but you kill FL's lead sister ..you kill ML's childhood friend/vamp,who weren't supposed to die .. you add more characters and kill them as well ... What about these people ??? Their destiny doesn't count ???
**I WANT JUSTICE FOR THESE SIDE CHARACTERS **

as we move away from the obvious mistakes in the plot we see the story started on a good pace .. leads were bright and comic ... Then as we finish more episodes they started becoming more and more hopeless and stupid ...they can't actually do anything to atleast try and make a difference. Anyways I think thats the fundamental rule in drama world you have to leave the logic out as you enter the world ...

In my opinion the cast was very impressive I didn't find any character from leads to vamp and support roles who doesn't fit the scene.

You can try watching it but it's one of those series which are more likely to be dropped around 15th episode ..there is no juice after that ..just a drag
