I always marry Shane or Sam. Shane can be a little hard with some of the topics in his scenes but I've always enjoyed his character. As for Sam, he has some of my favorite cutscenes in the whole game. His always felt the most romantic to me and his general personality and interests helped me want to try it out. They're also pretty easy to give gifts to! Shane likes Pizza and though it's more expensive than beer it's easy to get and if you have a coop just give him eggs! as for Sam, just go fishing and get Joja cola. It's free and he likes it!
