Not sure if u have already confess or not, but if u haven't,
here's some things u can put in the scrap book of confesison. Put
some pictures of u and her together inside the book, and maybe add
caption to the pictures like "I wish I can wake up everyday knowing
how blessed I am with u by my side" or something like that.
Or u can also find out what her favorite songs are, then link some
parts of the song to what you wanna say.
Hope u succeed! Because I think it is a very unique and innovative
way to tell someone u like her.
