Bloodthirsty Frenzy

Some people say that all people in society will hide another side in their hearts that is incompatible with their appearance, but some people hide it deeply, while some people hide it shallowly. And this is not something that people need to worry too much about. However, once your other side is emphasized to a certain extent, even more powerful than the main personality, split personality will occur. Yu Yun, the protagonist of the story "Vampire Frenzy", is a tragic character who was tortured due to split personality. Perhaps, his world is no different from the walking dead. How can we get him the redemption he deserves so that he doesn't turn into a bloodthirsty man who eats cannibal corpses?
