Is this webtoon already complete? If it is, where can I read it??

Sadly no. We're up to date with the webtoon. There is a novel though, but I don't know if it is completed or where you can read it. sorry

Thank you so much for replying. Is the title of the novel the same with the webtoon? I'll try looking for it.

It should be, although sometimes I see people refer to the series as "who made me a princess"
