interesting

A nerd boy attacked by electricity when he tried a machine promoted by his girl-college friend. The boy got a weird condition when somebody touched him. Everyone will have 'pleasure' when he/she contacts the boy's body and it fluids. Then, this is an erotic manga, mostly smut scene, explicit sexual content, and full color.

What will happen when two popular boys with their different "skill" meet each other.

the 1st chapter is interesting even though It is little bit confusing

a boy with extra blood production in his body meets a half vampire boy

I didn't understand the story in the beginning. Then, I get the 'message' idea later. The Puppet Master had the most tragic romance story in the end of the manga.
