If the player is gaining weight they should be able to go to the date events solo
Dating with yourself huh?
The Player can visit all the places in town alone. Fitness activities have even more affect when you work out alone!
All the town events can only be attended by pairs.
imho the above should stay that way!
Starting Day Offs alone, plus the opportunity to meet and pick up "special" girls at those locations, would certainly be interesting!
I'm sure there will be more activities for the player alone in future.
