How glorious is this manga! It's like a science experiment to see how two people with conflicting personality disorders react when they collide head on with each other. Adachi is completely doomed to suffer in this situation. It was wonderful to see her react honestly to what is she is experiencing. The raw power of her crossing the threshold of no return with the force of a freight train had me gasping. I felt like the author took a brave step artistically with this scene and pulled it off beautifully.
I think the most fascinating part of this story is Shimamura's internal dialogue, dissecting the roles people play around her, including her own, with a cold, unflinching eye that contrasts sharply with her adorable exterior. I find her to be a bit of a non-violent psychopath. She reminds me of Patrick Bateman in American Psycho, sans the violence It's fun watching her suitors try to connect with her emotionally when we know there is nothing to connect with. If Taru-chan could read Shimamura's mind, she would probably laugh and say "wow, I dodged that bullet!" and be done with her as a romantic partner. But what if Adachi read Shimamura's mind in the gym at the start of their relationship? This girl who seemed to have the promise of saving Adachi from her empty world of nothing, only to discover that Shimamura was as empty as the world is. What would Adachi have to live for then?
