summary. reader gets into trouble after an encounter with mean girls
The library smelled of old paper and wood wax. It was a place where you liked to take refuge during breaks. You were the “good student” in the class, always polite, focused, and with a perfect report card.
But today, everything changed because of a single gesture. When you left the central aisle, your shoulders brushed against two girls from your class. They were the same ones who liked to hang out in a group and nitpick. A barely noticeable bump… and yet they made it personal.
They followed you around all afternoon, saying mean things to each other. When the bell rang, they waited in the hallway, leaning against the lockers, looking relaxed.
"We'll take care of your case," one of them said coldly.
You clutched your bag to your chest, your heart pounding. The words were jumbled. They were threats. Jabs to make you crack.
What you didn't know was that Changbin was putting his papers away in his leather bag a few feet away. He was a music teacher. He rarely walked down that hallway at that time of day, but today, fate decided otherwise.
A loud voice had caught his attention. Not a scream, but that sharp, mocking tone he recognized well—the tone of students who think they're untouchable. His heavy footsteps echoed on the tile floor.
When he saw you, trapped between the lockers and the wall, his eyes darkened.
“What's going on here?” His voice boomed loudly.
The two girls backed away, less confident. She said something about “just talking” and left.
Changbin put a hand on your shoulder. “Come on. Let's go for a walk.”
You nodded, your throat tight. On the way, he didn't say anything, but he seemed attentive, as if watching for any sign of discomfort. In the empty music room, he put down his bag and invited you to sit down.
“You can tell me if something's wrong, right?” His voice was soft and reassuring.
You hesitated before telling him everything, the words coming out in waves. He listened, arms crossed and eyebrows furrowed.
He said, “Okay. I'll take care of the rest. But don't let this isolate you.”
You smiled slightly. “I promise.”
The next day, Changbin dealt with the situation quietly but very effectively. The mocking looks had disappeared, and the library was calm again.
This time, when you sat down between the shelves, you felt something different: you felt safe, and you had the impression that someone was watching over you.
