He had a gift. He can see and communicate with spirits and souls.

But it was also a curse. As they can inhabit and possess his body anytime they want. 

He found a way to get away from it. From them. The power to block proximity of these otherworldly entities.

He finally found peace from these encroaching souls, returning his life back to normal.

Until she appeared inside his apartment.

She didn't know who she was. She didn't know what happened to her. She had no memory. 

And she's a spirit. A lost soul.

A soul that kept on inhabiting his body to search for hers, returning him to the nightmare he once had of being ridden with trespassing ghosts that he keeps on waking up inside a mental institution..He couldn't count how many records he already have from mental hospitals to police stations. He would never want to go back to that.

He never wanted this gift. He only wanted a normal life. A life where it is not mixed up with paranormal existence. He had to get back with the witch who had taught him and gave him the talisman to keep them off him,

This time, he needs a stronger one.

To get rid of her.
