what you say doesn't make sence.
*sense
It said that his sickness was "love sickness." Basically, he was in love with Mizuki, that's why he wanted to watch him masturbate and couldn't stop himself from touching him. He was never actually sick, he just used that to get him to come work for him.
What kind of sick Sou have that he love to watch Mizuki masturbate. Not satisfied with just masturbate Sou touch Mizuki front and back too. Weird habit if not watch Mizuki play with "his own thing" Sou will sick.
