I think that's more a function of easy exposure and constant bombardment by English medium content that makes it less strenuous on your brain's language center to make the necessary connections to retain it effectively. I felt the same way about Japanese because I consumed a lot of anime and other Japanese media as hobbies I enjoyed. However, it is objectively a harder-to-learn language than Korean, which I had markedly less success with. And I don't think I have some kind of untraditional language processing algorithm in my brain.
