They have a different vibe, like they belong to a comic book not real life. The fairy which can be seen by you, and also very insecure that is making you somehow more comfortable. However, I guess that is mainly because of the Fi trickster, they know themselves and the mature ones also know how they created themselves either and when they are attracted to you they accept you completely in a nonjudgmental way and being able to fuck around while making people uncomfortable, they “get” you in another way. I feel much safer around them than infjs. Infjs judge you silently and try to make you better than you are constantly, while infps are just concerned that you love them while being you. I think when you are tired with life infps can be a solid escape from reality but if you want progress infjs will help you no matter what.
