Sayhi

I'm looking for manhwa I think it been so long I can't remember all the details.

Mc hides his identity and wears a mask at the very beginning. He was put in trial after he defeated the final boss. Pretty much people want him gone/dead because they don't need him anymore/scared of him.

He voluntarily gave up his powers and left but soon after he gains a new power he turns into as monster. Anyways right after he leaves he came to a city and met a girl and her disabled sister.

A few chapters later disable sister turns into a plant monster and attacks the city and prove they still need the masked here(MC) she didn't kill anyone and dies at the end.

Hi I'm looking for a specific Manhua similar to beauty and beast.

I only remembered the male leads lol the first guy was a white tiger, second guy is a wolf and last is black snake.

I really can't remember much and it's not beast consort
