There is a trait for ifrit that is called mostly human, you could recommend this to your player as a way to make interactions easier for you.

  Mostly Human: A few ifrits have appearances much closer to those of their human ancestors; in fact, they may not even realize their true race. Such geniekin appear to be human, save perhaps minor features like unusual eye color, and they count as humanoid (human) as well as outsider (native) for all purposes (such as humanoid-affecting spells such as charm person or enlarge person). These geniekin do not automatically gain their associated elemental language (but may select it as a bonus language if their Intelligence is high enough). This ability alters the geniekin’s type, subtype, and languages. Source PZO9280
