Psycho Game

My name is Gianna Selina Domingo, 17 years old. My life is simple and quiet. But it all changed when I enter the dark university.  Dark means no light, and that university too. Akala ko magiging maayos ang pag-aaral ko dito.  Ngunit mali ako. They told us that were safe here, that no one can ever harm us. Buti na lang hindi ako naniwala. One of us could be the killer... That's what they always say. Maybe, One day you'll just realize that your one with the victim. It all started when I received a red invitation... They taught us how to fight so we can survive. Pag mabait ka, mauuto ka. Pag tanga ka, patay ka. All you need to do is to survive the b****y game. *** There are  6  rules in this game...  You all need to follow what the rule is unless you want to die. RULES: 1. Open all the doors and windows at your appartment when the time is 12 am. 2. You can use knives, g*n or whatever you can use for killing the killer. 3. When you found out who's the killer was, you can't tell anybody. You need to be quiet. 4.No using phones, or anything that you can use for contacting others. 5. Don't ever kill other people unless you already found out that she/he is the killer.  and LASTLY... 6. Survive the Psycho game. isa lang ang sinasabi nila sakin, mas maganda daw kung uunahan ko ang killer. Pero pano? Kung hindi ko alam mismo kung sino ang killer? Everyone says, Don't TRUST anybody. because, even if she or he looks kind, they can be the killer.  Were all 15, but one of us could be the killer. And that's for me to find out... Who really is the killer?
