I think it was something like, he wished for chiwoo to stay with him,,,, and then the wish came true and chiwoo became an orphan with nowhere to go except back to hwan,,,, yikes JWGSJAGAH
tbh I don’t think he actually did actually but he did wish chiwoo would stay with him if I’m not mistaken and his parents coincidentally died after he said that-
This is just my guess. but at that time, Hwan found or was found by moony and used his powers of creating monsters to do away with chiwoo's parents.
wait for those saying that hwan killed chiwoo’s parents can you explain why? bc i’m over here thinking his five year old ass killed them himself LMFNSOWNAK
