I received another letter from the masked girl
I'll write it down below:

"Guess someone is getting good at this game but it is far from over.
Next level will be harder to you but I won't tell what it is.
some people tried to end the game by the rules, others just ended the game on their own way.
can you finish it by the rules?
you have 16 hours -DD"

After reading that, I thought that she wanted me to guess something.
Like always, I went out on a walk to think, she didn't even give me a hint, what was I supposed to do?
My thoughts were cutted when I heard a voice say "you seem lost in thought, is the game too hard for you?" I looked to the place where the voice came from to see a brown haired girl with brown eyes looking coldly at me, she was familiar, I have seen those brown eyes somewhere before... Then her eyes turned to someone else and I saw my best friend's enemy, Lisa Johnson, the worst of all, we never liked her.
I stared at the place the girl was standing to see that she was gone, maybe I was just seeing things.
The person that I hated was now in front of me and began telling bad stuff about my friend like "I'm glad she died, less one loser in the world" I got tired of listening to her and walked to a quiet place but she followed me, it was a abandoned park, it was old and if someone leaned against something without looking at it first, would die if they were not lucky, and, right in front of it, was a house, it burnt 3 years ago, a family lived in that house, but the body of the only daughter was never found so no one knew if she was dead or not, I think she attended the same school as I do but I can't remember, it is said that the girl killed her parents before burning the house and before destroying the park that belonged to the family and that one of the girl's victims broke the neck while trying to escape and it is also said that the girl is still around that's why no one dares to come here, they are afraid that the girl would come to kill them, I didn't believe the rumors and I come here almost everyday.
So I thought that Lisa would be afraid and would be gone but I was wrong "you killed her didn't you?" she asked "why should I?" I asked, her reply made me go crazy on that moment, I don't even want to write it or remember it again... I jumped on her and punched her over and over again, she was able to get on the top but I dodged her moves and we began rolling while fighting.
When she got on the top again, I pushed her away, she began bleeding and her blood fell on me like rain, I rolled to the side, made sure nothing was there and stood up. She got stabbed by a sharp edge of the old swing right on the heart, I was shocked and afraid, I killed a person...
I saw the same girl from earlier and then heard a noise, I looked to see if there was something behind me but there was nothing but a black cat, then I looked to the girl but she vanished again this time leaving a letter behind.
I picked it and read

"congratulations, you're going to the next level, Mary.
-DD"

It was the Depressed Doll again, wait... That girl... Was she the Depressed Doll without her mask?
