"You" - Piano version

[OrochiKira537]

So I'm trying to learn this song, and I'm really having a hard time playing it. Can any piano expert help me here, if any? Just give some tips and advises on using fingers and memorizing notes, etc.

So here is the song I'm learning right now:

Anything would be very much appreciated... even trolling.
