Review Detail of GardenDevil in I Became A Mighty Lion

So I was like “oh hey, a novel where the mc reincarnated into an animal. This should be a fun read” But the author had the bright idea to make this novel a tragedy. (If you’ve watched akame ga kill) the mc’s half sister got sheely’ed and chelsea’ed. meaning she got eaten until only her head was left. I thought that was it but the author did it again. This time it was someone younger than the mc who the mc brought along with her mother but the mother got killed protecting her child, said child was then killed because she thought the mc can protect her. Then the mc had the bright idea to turn the child’s killers into his followers. I stopped reading after chapter 200. i don’t want to have depression because of this.
