I should have planned for this. If lovable scamp is already taken (and why wouldn't it be), I'll take good-natured fool.
I'll be playing the "glasses-type" playbook. I'll always be illustrated with large opaque glasses and I'll be holding a clipboard for some reason in every scene. I get +2 to INT checks and gain experience any time I show humanity by blushing or showing interest in a person or something trivial (not academics.) When leveling up, I can take the feat "Gleam" which allows me to have surprising knowledge on a topic which I explain in-depth. Nobody else in the room can know more about the subject than me in that moment.
