This bizarre 'something' seems to desperately want to be treated as a father. Guest is pretending to be fooled and treats him like a father.

This is because no one knows what that strange entity might do if it thinks its disguise has been compromised.

Guest's father was originally an ordinary man, but he died after being swept away by river water on a stormy day.

Surely all the villagers mourned over his bloated corpse and held a funeral together. Yet, on a sweltering summer day, that man reappeared as if nothing had happened.

With a somewhat unpleasant and distorted face, speaking in the language of beasts instead of human words, he acted bizarrely like a father. However, Guest wisely pretended to be deceived and has been playing along with this strange entity's house-playing until now.

No one knows how long this play will continue...
