Hello everyone, i would love to say that from today i will rewrite my book for a better fondation because, it was my first time writting a story and i never put my brain into it so if some people have suggestion like harem or no harem, if no harem i will make a cold mc and if harem then we will see.

i would love to know if people want that mc is a god that reincarneted in the mortal world or a normal person that got 3 or 5 wish (super op or op but with challenge)
