Do you have any save files that end the characters without getting married?
"end the characters" implies they all die or leave the game
you have to get married to finish the game and unlock ng+
bad endings dont count like MC getting killed by Danny or Dwayne its a game over
if you mean a save with all character events completed but no marriage proposal
Well that's mostly pointless unless you want to see all the marriage variations
I'd have to do another playthrough to provide a save like that
or you might be able to find one in the game thread I'm certain people have posted some
