Ok, so, I can’t remember much, but I do remember one arc. it was a zombie apocalypse arc and the MC ended up making the cure and used the ML’s body to do so. Turns out, though, that world was rejecting MC or something and he was coughing up blood at every other turn AND the ML knew what was going on the entire time (he appeared as a ‘ghost’ that followed MC around). MC dies in that world but SURPRISE MOTHERFUCKERS he re-transmigrates into that world. ML remembers the first go of the world, as do a bunch of different people.
