I read a novel like this. The personalities could even talk between themselves. They were lovers and the main personality goal was to get a body for him.
that seems interesting, what's the novel called?
It's not completely translated. The name is "Supernatural movie actor app" here is a link where you can read it:

oh, that's okay. tysm!
It was a really good plot but the personalities are the cliche`. Soohyun and Sooha should be more thankful to Ray. If it wasn't for him jumping Soohyun in his sleep they might not have hooked up. ^^ It's always the one who's working hard that ends up screwed over...
I'm still awaiting the day where a character with multiple personalities becomes two separate beings and their partner is cloned. Happy Ending x 2!!
