Glad you've enjoyed! If you haven't already spoken to Kahnnonkahn and Credence, they can give you hints on how to complete each level, including the neighborhood. If you still need help:
The fastest route to complete the level and find your boyfriend (you figure out he intends to propose):
Starting on Oscar Road->Blarney Drive->Edwin Drive->Yallow Road->Manchester Terrace->Edwin Drive->Sarbon Road->Lockley Drive->Alabaster Court->Vesper Street->Edwin Drive (Make sure to speak to the residents on each road as you move through them)
Be prepared for cuckolding, thrupling or relationship drama depending on your decisions.
