Ireon Gwaoeneun Sireo!

Do-Young, a repeat student looking for a private tutor to help him get into a Korean university, decides to take lessons from his class president, who was introduced to him by a high school friend. However, Ha-Jin, the class president from the first semester who disliked him, joins as his tutor...

Do-Young is constantly distracted by Ha-Jin, and Ha-Jin suggests canceling the tutoring.

"If I misbehave again, you can hit me, punish me, or whatever you want!"

Do-Young, unable to give up on the tutoring, says these urgent words, sending the class into a completely different direction.
