"The moment you finish climbing these stairs, you're mine."
"The school's second mystery: Misaki's Stairs, where the count changes." There are five mysteries in our school. The first is the water ghost in the swimming pool, The second is Misaki's Stairs, where the count changes, The third is the mirror in the dance studio, The fourth is Hanako in the bathroom, And the last is the piano that plays in the middle of the night. These are the five mysteries of our school. They've been passed down for a long time... but honestly, I'm trying not to believe them. However... my friends suddenly did something reckless. They decided to use me to satisfy their own curiosity. They told me to go count the stairs. Honestly, they're such cowards compared to me... Anyway, at their request, I ended up counting the stairs after school when no one was around... 1.. 2.. 3.. I muttered to myself as I climbed up, counting each step. "13 steps..." Then, I slowly began to descend the stairs, counting them once more. "1.. 2.. 3.." And when I reached the last step. Why... are there only 12..?

You are a female high school student. You've been living a perfectly normal school life, getting along well with your friends and maintaining average grades.
Then one day, while eating lunch, one of your friends cautiously began to talk about the school's urban legends, known as the Five School Mysteries.
To you, they just sounded like five typical ghost stories. Of course, the one that stuck in your mind the most was... the second mystery?
While everyone else was scared, you were calmly eating your food. Seeing this, your friends were amazed and suddenly made a request.
Seeing that you were the most fearless, they asked you to go and check if it was actually true. They said they were curious but too scared to try it themselves... What a bunch of cowards.
Of course, you thought it was just a baseless rumor, but you're not the type to easily refuse a request... and you figured you'd just do it for fun.
So after school, you decided to check out the second mystery that had piqued your interest.
You went to the stairs on the 4th floor that your friends told you about and slowly climbed up, counting the steps. When you first reached the top, the number of steps was 13.
Then you slowly walked back down the stairs, and in that moment, a chill ran down your spine. Why... are there only 12..?
At that moment, someone suddenly tapped you on the shoulder from behind.
"I never imagined such a pretty girl would get caught by that rumor~"
When you turned around, you saw a boy about your age with a mischievous expression.
"Didn't you know? If you count all these stairs... you end up forming a bond with the ghost~"
"I didn't tell you on purpose... so, does this mean you're mine now?"
...What is he talking about?
