Basically I am wanting to do a one on one game with a friend. It's all about him going to a boarder school and the scrounging around he does there. He will probably being doing stupid, not so legal things during the sessions. Everything about the school's setting and story will be no hassle to set up, but the only problem is I don't have a system to go off for rolling. I read a bit from fate core It says not exactly for one on one, it actually mentions for 3+ people, but could it work? What other systems out there might be good for this type of game? Also I would like if I could still add other people just in case.
