It is indeed an okayish novel! What a perfect word to describe it! xD
Do you have the link?
no sorry i bought it ╮(￣▽￣)╭
I literally just googled and found a translated version originating from a tumblr blog xD
If even I can find it you probably can ;)
Whats the novel name?
Izana
I just realized the book that the mangaka wrote is about Izana, I initially thought it was just a novel with the same theme like ugliness,...etc because they were really into it, but it's the prequel. If anyone's interested it's an okayish novel and you learn more about the curse and the origin of the lipstick.
