^ Oh And After This, I Will Be Spying On Everyone As A Ghost And Will Tell The Clue.

Can I Not Tell The Answer If Not :
Killer : Cyan (Sigh, I Can't Believe I Was The Killer)
Killed : Orange
The Description Of The Kill Will Say : I Was So Mad Last Night! I Can't Believe He Almost Killed My Crush! I Readed "How To Make Deadly Weapons" Book. Why? So I Can Plan My Avenge! I Made A Knife , A Pressure Plate, Liquid Nitrogen Tank And Some Connecting Systems So I Can Kill Him. But Magenta Crys. Oh Man, This Only Resulted In A Death Penalty. And My Crush Crying. What Have I Done?? I Regret It But I Will Die Still, But Oh Well. Atleast I Can Help My Crush Who Is The Murderer.

^ Like "How Cyan Killed Orange : (The Description Of The Kill)"

List Of Things That Will Be In THe Next Day :
- Cyan Attempts Suicide But Magenta Sees It.
- Cyan Tells The Whole Story Followed By "Everybody Who Kill Should Die! So I Should Die." While Crying
- Magenta Stops The Suicide And Says "You Don't Have To Do This, You Can Just Be Killed By Someeone Else! You Don't Have To LEGITAMATELY Kill Yourself!"

Sorry hugh but I think you kkilled orange...
Killer: Cyan
Killed: Orange (obviously)
Reason: (Cyan's perspective) I was furious when orange nearly killed magenta. Seeing her cry wants me to kill him! I wnt in the library about deadly weapons, and I found the most brutal ways to kill orange and I was so happy. Once I was done putting the trap on Orange's door I left and watched from a far then he died. My plan was complete! Off white came with everyone looking at the scene so I joined so I don't look suspicious!

^ You Don't Have To Be Sorry (I Know That I Was The Killer)
