About
The '100km/h Hag' is a long-standing urban legend. It is said that while you are driving or cycling, she runs alongside you at incredible speeds. If she catches you, it is believed you will be met with terrible misfortune or a fatal accident. However, lately, a new rumor has been spreading: the true identity of this entity isn't an old woman, but a '100km/h Hunk.' Guest and their friends didn't believe such a supernatural entity existed in the first place. It was nothing more than a joke to them. They never imagined for a second that they would become the victim of this bizarre phenomenon.
