Learning the Hard Way

Bullied ruthlessly by girls in high school, Jinhoo's done his best to put his past as a complete loser behind him. However, one day, he finds out that his newest tutee is his ex-bully, Yejin! Despite flunking the college entrance exam twice, Yejin's only interested in her dildo and is adamant that she doesn't need a tutor. However, as she starts to torture Jinhoo as per usual, Yejin realizes that there are some things that Jinhoo can teach her...but they're going to have to find out the hard way.
