In Harvest Moon: Back To Nature the Girl the game ends when you get married.
You will see a scene of the bachelor proposing to you and then if you say yes,
the following will happen exactly 1 week later. After this scene the game
ends. I only have seen the Cliff scene which you can see below. It
shows both what happens if you accept or turn him down. If you would like
text of the other endings please go to my affiliate Ushi No Tane's page on it at

of the four other endings or even just one of them please let me know.
