Yeah, you have to finish the tutorial, but yeah, just use the cheat menu to lock the stats and give yourself some money (but don't forget to work), and that is all you really need, the rest is story based, other than talking to Sophie 5 times for the sauna.
Well, Sophie, I love her coming out of the shell and she is one of my favorite characters (2nd behind Veronica I'd say), but let's be real
5 times "Hello" - *blush*
5 times helping her on the machine
5 times sauna sitting in the other corner
5 times sauna next to you
5 times sauna without towel next to you
5 times sauna with "exercise"
