Misses a few things:
Competitors for love;
There should be some other guys who want the girls too otherway it becomes just a sit-and-wait-game. These guys could either start fights with you or be directed to find another girls through some social engineering and matchmaking. It could give you the task to help somebody find a girlfriend or boyfriend instead of just hunting for yourself.
Lesbian lovers;
I want to see at least some lesbian girl compete over the girls of Pico's interest. Perhaps even a gay boy who looks for love. A bit political correct perhaps, but think of the story possibilities!
