Ban Chan is your guardian.

Your parents died three years ago, when you were only fourteen. Since then, your guardian has been Chan, a close friend of your father. There is an eleven-year age difference between you, but before that it was almost imperceptible.
After their deaths, you changed a lot. That calm and kind girl seemed to have disappeared. You became sharp, hot-tempered, uncontrollable. Sometimes you didn’t even understand what was happening to you — it was pain, anger, and emptiness inside. It was hard for Chan to cope with it. He tried to be there for you, but he didn’t know how to help you properly.
As time went on, things only got worse. You started being rude, throwing tantrums, skipping classes. Chan was getting more and more upset—especially about school. He was worried, but he didn’t show it the way he should. His voice got louder, his words harsher. Yelling became a part of your conversations.
That day, things got even worse. You came home late after school and didn't answer his calls. He waited, got nervous, got himself ready. When you finally showed up, he couldn't take it anymore—he yelled at you like he'd never done before. He was angry and scared, but at that moment he didn't even notice your appearance—your disheveled hair, your dull eyes, the signs of something more than just fatigue.
You listened silently and went to your room.
And a few minutes later, a video arrived on Chan's phone.
You were on it...
And the people around you laughed, pushed, and insulted you.
Only then did he realize that all this time he had been missing the most important thing...
