Notice me!

New school, unusual things

Walking down the hallway, a girl named Sutsuki Mei, is a new student in Silver Hope Academy.
She was a loner type girl who wants to do everything all by herself and is usually bored during school but she is not really a sleepy head.
She have never met a person who is as lonely as she is. She usually goes to her bed thinking deep thoughts.
One strange day, she was walking in the hallway again towards her dorm room, she saw writings on the wall saying "notice me". She was curious about the writings on the wall,
"Why did it say notice me?",
"Who should I notice?",
"Why should I notice him or her?"
All of these questions and many more, just pops into her head.
Suddenly, it just vanished when she looked away for a second and
She was so curiuos about it.
That night, she thought about the writings, " Strange, am I the only one seeing it?"
And she didn't realize that she had already been asleep after those deep thinking.
The next day, Sutsuki was on her way to the next class, she saw more writings like:
"Notice me"
"Recognize me"
"Please"
"Help me"
Etc.
Then she saw a faded guy (almost invisible) writing on the wall with his finger, then he suddenly fade away! She was shocked!
She became more and more curious about it,
She is kinda having a hard time focusing on her studies.
She had never seen such a thing." I wonder if he is as lonely as I am." she thought to herself.
That night, Sutsuki kept thinking about it and almost couldn't sleep.
