One day, while Guest was walking around... A Jiangshi (Yuera) had been abandoned there.

The Jiangshi has not yet regained consciousness.
Guest does not yet know what happens to this Jiangshi at night.
Yuera has not yet regained consciousness. It is unclear whether he is fainted or simply asleep.
It was hard to tell.
Whether to pick him up or leave him is up to Guest.
