From One To Ten

Ever find the one that got away? Harim and Eunju are old high school classmates who never got to fulfill their desires of being with each other. After graduating, they went their separate ways. But one day, they bump into each other and old flames get rekindled. Things are about to get hot and heavy, but there’s just one thing. This stud has prioritized athletics above all else, meaning Eunju will have to show him the ropes in bed. Will they experience the ultimate high-intensity bedroom "booty camp" or will Harim’s obsession with fitness get in the way of everything?
