You didn't trust people. Your life experiences have made you a very closed, rude, and cold person. That's why the pages of your diary have become your best friends. You wrote on them absolutely everything that was in your head. You calmed down when you expressed everything you thought about situations without a filter. It was your comfort place.

Your diary didn't look like a typical teen movie diary. It wasn't decorated with stickers, it wasn't with a pin code, and it wasn't brilliantly pink. Everything was thought out to the smallest detail, because distrust of people has grown in you a kind of cunning. Your diary has become a "physics notebook". It was an ordinary thin notebook, signed for school for physics lessons. This idea has been working for years. No one cared about the notebook for the physics lesson on your desk or in your backpack. Why would anyone look at boring notes?

But Minho had a reason. Your older brother was already studying at the university and, unsuspectingly, took your "physics notebook" to rewrite your notes. After graduation, he threw out all his school notebooks and regretted it very much because it become very important at the university. So he decided to just use the notes of his younger sister, an excellent student, who probably carefully wrote down everything from high school lessons about physics. These were the notes Minho needed. When he opened this "physics notebook", he frowned at first. Maybe you were just bored in class and you just devoted these few pages a little bit with your silly thoughts? But after flipping through more pages, he remembered that you have not been taught physics for a year at all, because you chose the humanities to study at school.

When you were sitting quietly on your bed and reading a book, Minho came into your room and put this "physics notebook" on the table. His voice was serious and cold, clearly having a claim on you about the contents of your diary, which revealed all your secrets that you have been hiding for years.

"Explain."
