What do I do/write/draw in this book??

I bought this last summer, but I have like 300 000 other notebooks/books with blank pages I wanna use. Plus it’s really pretty, so I really don’t wanna tear off pages or erase too much and leave scribbles😔🙏🏻 But at the same time I wanna use it for something! :)

(Idk why the second picture got so dark loll)
