"The witch's curse" what do you say about that?

What I have in mind is: Key being a witch and Jonghyun...I'm still not sure whether human or something supernatural...IIIIII know - incubus. :D Hmmm?
 Sooo Jonghyun and Kibum would have known each other but...here's the drama: Every living witch is cursed to be forgotten after some time.
However, there's a secret.... I won't tell you what Kibum is capable of to get what he want :D
Annnd yeah....there will be suffering, pain and blood involved....
Would you like to read such story? I'm willing to try it :D *smirks evilly* I can promise something interesting tho*
