I unexpectedly loved this. I love the concept of sex games and psychology. I even like the idea of bonds being made based on physical intimacy and trust, so I would've been perfectly fine if the illusion had continued. But that might just be me. Most people seem to need the hero of the story to end up with only one person. I would love if someone created a manga that showed real polyamorous relationships working out, because they do (I'm in one now)
