Oh, Chunja Chunja! High School Bullying

From Fateful Encounters:
Oh Chun Ja, a timid girl, has just transferred to a new school and started her new life. Nevertheless, the first day didn’t come easily as she thought. Not only did she go to school late, but she was also bullied again. To make it worse, she had to sit next to the Devil King Lee Seo Lu. And now he even offered to help her by teaching her how not to get bullied. Thank goodness that the young and handsome gym teacher is there to make Chunja’s life a little bit brighter.
