Joining a fandom that is new to you but well-established is like going to a restaurant with a sign outside that just says “Food served here” and asking for the chef’s special without looking at the menu.
Fifteen minutes later a waiter just comes out like “Uh, who ordered the middle-aged man shrieking ecstatically in German while being pounded in the ass by an enormous Russian?”
And you just have to put your hand up like, “I guess that was me. I, apparently, ordered that.”
(Meanwhile, the cook’s in the back throwing another plate on the counter like “A Red Oni trashcan and a Blue Oni trashcan in a hopeless Foe-Yay spiral, pick it up!”)
