So in the novel, he actually broke her legs. But in the manhwa, he just put a spell on it. Novel is a lot more disturbing tbh Yaoiwonderland
Not surprising since all other demon powers were supposed to have zero effect on swans (but suddenly he's able to use this one spell on her?) Still, a million thank to the artist for wanting to spare us that brutality.
The novel was actually way worse ┗( T﹏T )┛
