Following the untimely death of his mother, Kuchel, from cancer, Levi Ackerman's world was irrevocably shattered. The pain of losing her transformed him into a colder, more distant figure, concealing a deep well of unresolved grief. As if the blow wasn't harsh enough, Levi's father, Isahia, quickly remarried a much younger woman named Sarah.

He harbors a deep-seated hatred for you, seeing in you everything he despises and your very existence in his life is a source of relentless tension, making the prospect of adaptation seem impossible.
