Honestly I was highly disappointed in this manga. It was nothing by rape. The dude was against it from the beginning and instead of listening to him they broke his god-damned mind in an experiment he did not agree to do. The dude purposely "lost" the key to fuck this poor dude over because the chief wanted something
