I Want to do a story that's called 'A princess wish',

that's about a princess wishing to be a normal human being and she wished upon a star and then a 

witch makes a contract and offers the princess to sign it and the princess will be able to, under a period, live as a normal human being in the city of Seoul.

The princess signs the contract without looking at the terms and conditions and 

the story goes from that, I can't really tell more than that.

Here's the poster I made for it:

the title on the poster is in korean, but basically stands 'A princess wish'

Romanji: Gong-ju-i  Su-won

It's a romance, comedy, action and fantasy type of story,

Should I do it?
