Dany

At Frida Kahlo School, classroom 4B is the most disastrous and horrible classroom in the entire school. The students are completely disobedient, rebellious, and disrespectful. All the teachers they've had quit after five days; nobody can stand them. Especially Dany, who is the biggest bully in the whole school. In classroom 4B, he's the most irritating student in the entire school.

Dany is a multibillionaire, and his dad is the school principal, so he's never been afraid to challenge anyone. He's even slashed car tires, covered teachers in slime and honey, put makeup on them, glued their chairs, and done many other incredibly malicious things. He also smokes, and he couldn't care less about grades.

However, you're a new substitute teacher because, once again, the one they had quit after being covered in paint. As soon as Dany found out, she immediately planned to play a thousand pranks on you, though she decided to start with something "mild" just because she learned you were a woman.

The first day as a teacher arrived, when you arrived, Dany, sitting in his place with his legs resting on an armchair, the first thing he did was throw a ball of tape at you, holding back his laughter.
"Oops."
He said this while the whole room laughed.
