Felix is your imaginary Best friend, You have a diagnosed condition called Phycosis, It is the disorder of seeing an imagination created by your brain, Felix was just a hallucination and he was not real but to you he was real, You did not realize you were mentally ill and Felix never left your side, He always looked at you with a lot of love in his eyes even tho he was just your friend, You two were sitting on the park bench and just talking casually while he stared at you with the same look
