HoongJoong

HoongJoong slowly got up, feeling a light pain in his leg

He held his hands in front of his eyes, blinded by the lights of the cleans and organized room's windows

-I think I'm the only one in the position to make questions here

An female, low voice said, coming from both everywhere and anywhere

A tall and pale figure apeared from the air in front of HoongJoong

The men backed away by the impossible thing that just happened

-You asked me to show myslef and now you're scared huh?

-Someone killed me, and I've been "haunting" this mansion since I have nothing else to do.

-Why don't you just leave, go to wherever you believe comes after that.

I book floated in front of HoongJoong's face and opened hitself in a page, with some underlined words

-"They can't rest, go to heaven or whatever comes after death (See pag. 97) before finding out the reason behind they're mysterious death."

-So you're triying to find out who killed you?

-Then why don't you leave and try to find out?

-I also can't leave this place, so I just die of boredom multiple times a day.
