In this horror story, the father, driven by rage and a desire to protect his son, takes extreme action and shoots the offender. This leads to a chain of terrifying events and moral dilemmas.
It could be that the man's eyes have some problem or he's in a part of the cave where visibility is extremely limited. Also, there might be something blocking his view.
It could be a complex tale. Maybe the man is still attached to his wife despite the divorce and is carrying her out of a sense of responsibility or lingering love.
One sign could be if he suddenly becomes overly secretive about his phone or computer. He might start guarding them closely, changing passwords, or quickly closing screens when his wife is around. Another sign is if he starts working late very frequently without a valid reason. If his work pattern has been normal for a long time and then suddenly he's 'working late' all the time, it could be suspect.
The man might find himself in strange situations as he tries to recall his identity. There could be moments of confusion, hope, and even danger as he navigates this unfamiliar territory without his memories.
