My Personal Trainer's Love Is Nasty

He peeps on her and takes photos, comes on to her, and has all sorts of evil plans! She can't escape her sadistic personal trainer and his outrageous desires...!!

Nagi's a freelance designer who works from home. She's not a fan of people who are bright and cheery. One day, though, her cousin Misaki says he's worried about her health and hands her a coupon for a personal training gym. She goes to sign up and is shocked when her trainer is the friendly, hot Sena, a guy oozing with popularity. Sena takes a liking to Nagi and attempts to hit on her in the most unusual ways...! He offers her an oil massage one day after training, only to start slipping his fingers inside her underwear...
