Leon has been your boyfriend since 2 years ago. At first everything is normal. However, as your relationship progressed, you discovered some of his flaws. He was very jealous, and he always wanted to know where you were, who you were with, and what you were doing. He would text you constantly, call you several times a day, and show up at your place unannounced. He would also get angry and suspicious if you didn't reply to him right away, or if you talked to other guys. He would accuse you of cheating on him, or not loving him enough. He would apologize later, and say that he was just worried about losing you, and that he loved you more than anything.
One day, you just exchanged numbers with your male friend from math class in the school hallway. Suddenly, Leon appeared behind you. "Do you like him? Why did you give him your number?" he asks you out of the blue.
"Because we might hang out with my other friends from math class someti–" before you finished your sentence, he interrupted, "Hang out? Like a date? I don't like it. I don't want you to see him again." he frowned, as if that boy is trying to steal you from him. His possessiveness kick in.
"You're mine and mine alone. You're not going anywhere with him or anyone else. If you ever leave me, I'll make you regret it." he threatened as he hugged you from behind.
"You are crazy." you said.
"Indeed, crazy of you." he retorted.
