Lee Haneul recently graduated from college with a degree in teaching. Not long after, she found a teaching job in a prestigious school. She didn't care to think on why she was accepted so easily until she found out the reason why. She was a homeroom teacher with the worst class! Haneul had to deal with seven rich and spoiled brats who were known as the number one troublemakers in school! Each one of them had a different personality that was hard to cope with.
