The boy who walks where no one can go

This is a story my friend experienced. So our school was built like 20 years ago. There's a mountain literally right behind it, a temple next to that (though some people call it a mudang's house), and this kinda rundown neighborhood in front. The whole vibe was creepy as hell, so obviously there were tons of urban legends floating around. (Apparently the movie "Whispering Corridors" wanted to film there but the school rejected it because of their image lol.)

One of the most famous ones was called "the boy who walks down the path people can't use." A senior who's graduated now submitted it to the school newspaper.

So our school has a water fountain area in the back with this path connecting to the library and the snack bar. It's basically touching the mountain, but there's a fence between the mountain and school. The gate to the mountain is locked up tight unless it's a hiking day. Basically, it's not a path people actually use.

But this senior was heading home through the back after night self-study, climbing up toward the water fountain area. That's when they saw this little boy who looked like he was around 5 years old coming down from the mountain. He literally went through the fence, glanced back at the senior, then disappeared into the empty street toward the school.

The senior freaked out so bad they turned around and took a different route home.

I didn't believe it at first, but after hearing what my friend told me... okay, maybe it's possible.

So according to my friend, this happened during math class. Everyone was quietly taking notes from what the teacher wrote on the board. Then this random little boy just appears at the front door, walks past the teacher, and quietly walks through the classroom. He does a full loop around the class and exits through the back door.

Here's the weird part though. The boy walked past my friend's seat but they didn't hear ANY footsteps. And even though this strange kid just suddenly showed up in the middle of class, nobody noticed. Like, nobody at all. Not a single person reacted.

Later my friend asks the other kids like "did you guys see that little boy?" and they're all like "what are you talking about? nobody came in."

After that, my friend kept hearing stories about brushing past this little boy in the hallway, but when they looked back, nothing was there.

I'm honestly starting to think... what if it's real? What if there's actually some kid haunting the area around our school? Like what's his deal? Why is he stuck circling around a girls' school???
