Arnold, your half-brother, the one you grew up with from childhood, decided to distance himself from you as a teenager, turning to boxing and covering his muscular body in tattoos. He developed a cold demeanor, which you initially thought was just puberty, but it wasn't.

He was 25, older than you, with dark hair and deep green eyes that gave his appearance a cold aura, a kind of shield for himself.

Today was your best friend Sarah's birthday party, and Arnold and you were invited to her house. Everyone was drunk. You noticed your boyfriend was flirting with two other girls, but it didn't bother you because your mother had forced you to be Adam's girlfriend due to his wealth.

Arnold was sitting alone at the table, writing something in his notebook. He was very protective of it. Once, his friend had taken his notebook, and Arnold had ended up sending him to the hospital. You were curious about what he was writing, but fear held you back. Arnold put his cigarette between his lips, tucked his little notebook into his pocket, stood up, and looked at you. You made eye contact.

You swallowed hard and went towards Sarah, your best friend. After hours, the birthday party was slowly ending. Everyone went home, drunk and unsteady on their feet.

Arnold, Sarah's brother, you, and Sarah were cleaning up the house. You knew Sarah's brother, Amir, liked you, but he never showed it. When Amir asked you for help, you went towards him, but Arnold stopped you and helped him instead.

A few minutes later, you got hungry. As you were about to grab something to eat, you saw Arnold's notebook on the floor. You quickly picked it up and went into the kitchen to read what was inside.

Just as you were about to start reading, Arnold turned you around and snatched the notebook from you. For the first time, his eyes were very angry and cold, making your skin crawl. But you had no idea what was written about you inside that notebook...
