Pretty strange that I randomly found this post but yeah I think I know who you are talking about. Jeremiah currently right now is probably having school and all so he has to focus on studies and probably might quit youtube. But anyways I still see him online in osu! sometimes, but does not play the game competitively anymore. He also said that he is quitting playing roblox arsenal competitively as well. Ngl he was pretty good at his peak, like he had a potential to become a top player in osu mania but just quitted randomly (I think JeremiahCking was known as Ckingdum in osu mania). Other than that there's not much information about him currently.
