Pain doesn’t affect Yoshie... no, that’s not quite right; it feels good! Sensei's forceful massages at the Seitai Clinic are the best. But Sensei's solemn and bone-obsessed son, Mikawa, is secretly listening to Yoshie’s breathless moans! Is it only a passion for bones that excites Mikawa? Yoshie soon realizes that pain in your heart isn’t the same as pain in your body.
