SooMin was 5 years old when she can see and talk to ghost. SooMin didn't had friends but she will always talk to someone that her parents can't see and they didn't want to ask her. But one time her parents will ask her who she's talking to? SooMin said "My bloody friend." SooMin parents was shock when she said that and they were worried about her. But what made her parents more worried but mostly scared was that she was crying in her room and she said 
"Mommy Daddy I'm scared, my friend said that she's gonna kill you when I'm not here with you." 
Her parents didn't believe her at all and like any other paarents will do (not all tho) they scolded her
"Ya! Why would you said that I don't believe you and where did you hear that word from ! you're only 5 years old!" Her mother shouted.
SooMin started crying.
2 years later when SooMin was 7 she made 6 new friends who are older then her and their names are N, Leo, Ken, Hongbin, Hyuk, and Ravi but for some reason they called their little group VIXX but she likeed the name though.

She was walking home because they wanted to hangout at her place. While she was opening her door to her house she notice that her parents wasn't there so she screamed out
"Mom Dad are you here?"
No reply, so she told the guys to stay and wait while she looks for her parents if their home or not. While she was searching the whole house she went to the basement, she the lights and the first thing see saw was her parents...cover in blood, dead, SooMin screamed in fear and started crying. VIXX came down to see what happen but when they saw her parents on the floor covered in blood they was scared and shocked but they told SooMin to go upstairs and call the police. The police came and took her parents body and said it was some kind of murder and told her to stay at her friends house. SooMin was crying but what caught her eye was her 'Bloody friend' smirking at her and disappear, she remember that her 'Friend' said that she was gonna kill her parents when she was not there.

She never told VIXX that she can see ghost or whatever because they're going to think she is crazy. And since that day happen she was living with Leo but of course the gang will always hangout everyday no matter what, but that memory will always haunt SooMin and she also wonder why she was born like this and why her 'Friend' wanted to kill her parents when she was not there. But she did warn her parents that she was gonna kill them one day when she's not there. But  now since years past and SooMin is now 19 and her friends are idols , now that horrible memory came back, and she is living with VIXX at their dorm. But she still never told VIXX about her little secret.

This part might be short but I'm trying my best and which I
