Private Tutor (Secret Tutor)

After Sangwon overslept on his college entrance exam day, he is forcefully enrolled in the private institute his uncle runs. On the first day of class, he witnesses the affair between his uncle and the math teacher, who just so happens to be his girlfriend’s mother. He gets a hold of a video of their secretive affair and blackmails his uncle into making a deal: let him have private lessons with the seductive Ms. Kim, and he’ll keep everything to himself. As Sangwon and Ms. Kim begin to dive deeper into the lessons, she starts to teach him more than just math…like how one student plus one teacher adds up to a super sexy steamy session.
