Eve's existence lies in the balance of his feelings. Feel the wrong stuff and your friend goes into the shredder. Hey, it's your fault. This is unfair.
@toastedguy I'd say it's because at the end of the day, even though it has a dumb premise this manga still manages to have a pretty interesting and enjoyable story
Why do people criticize this manga for not being an Ebinofest? Hell, the deal with Eve is pretty damn interesting and heavy, you just cannot fall in love in his position if that means killing someone.
