how to get past the buy page

Anyone know how to use that book about dating in the game (android version)?

5/5 would play again.

Someone knows where i can listen/buy/download this music?

To answer Pillowbull below me, StudioWhy is the one who made the actual game (And Tiarawhy is part of the team), they're still working on this. They released the alpha 5.0 at the beginning of this month https://www.ponywaifusim.com/
