Similar vibe like the occult or someone being possessed.
In HforR it is about a father that wants the return of his firstborn child who died and in Kampon it is the spirit of a deceased mother wanting to exist again by finding a new body to possess.
In Kampon, it is about a young child called Jade who turns up out of nowhere at a strangers home one night with the appearance of a little angel in her mannerisms and spoken words, but behind that facade is a little demon.
It seems the couple chosen are not chosen by random.
