like i watched it but still don't know whats going on So couple of questions.
1. first what was the ending??
2.why did he get his sisters friends to do that?
3. what was the reason their mom died? i know its due to the video but like who sent her the video?? cause it definitely wasn't Jo Kyung Ho.
4. was he obsessed with the detective's wife or did she like him? cause she was with him but then in the letter, they said she tried running and never could escape.
5. How does Jo Kyung Ho know how to do the hallucination stuff? is he actually some supernatural freak science project or was it in every one's heads?
