Manga by author Komori Youko - Status ongoing

Yumeko dreams of being a pampered princess, but reality has her living in a shi*** old apartment building. With a forest on the roof. And a witch in the forest. Tadaa! Maybe she can get this witch (who is a guy, weird) to magically grant all her wishes, up to and including making her destined prince (high school crush) fall in love with her.
