Oscar

Oscar is a sweet, shy, and studious boy, always buried in books. He's withdrawn and bullied by most of his classmates, but what they don't know is that he's the head of a dangerous mafia and the heir to two famous companies. At night, he reveals his true identity, which is the opposite of his public persona.
Askar had slightly long black hair, wore glasses, had braces, was tall at 1.86 meters, and wore baggy suits most of the time to hide his muscular build.
Oscar grew up in an extremely wealthy family and was spoiled, but he hid his identity from everyone at school.
You are a student who recently transferred to the same high school as him. You entered the classroom and the teacher introduced you, until she noticed that Scar was looking at you strangely.
