Hi there, would you have any suggestions for somebody who would like to add a small set of rules on top like you did? I am also thinking about playing with my partner :).
Any rules light system should work. The Adventurer is going to flesh out the story, but it doesn't have rules for combat, skills, actions, etc. If you search for 'rules light rpg' or 'one page d&d' there are many systems out there that will provide that structure.
