Sorry Not Sorry

Duchess Ariana Lee, president of the student council, rumored with her cold personality and one of the top students at the proud and peaceful school of Halil Stales International State University. She's not only smart but she is also the prettiest. No one made her lose her patience before. She is always on top of her class and is always calm and collected until a transferee came, Max Hugo IV Halil, the youngest son of the university's principal, a hot rich and a troublemaker student who will make her lose her patience. He might be a troublemaker, but he is also smart in academics. Smart enough to take her place as a top student. Has Duchess finally found her rival? Or not?
They always have arguments and Max is unstoppable when teasing Duchess. He made her cry one time and stared at her while his smile faded. He felt hurt when he saw her cry for the first time. Duchess walked away and students we're talking about him. He felt sorry seeing her in that state. He chased after her to apologize, "Duchy, I-Im so-.." he stopped when he saw his friends and remembered the bet. To make the student council president cry. "Sorry Duchy, not sorry".
