Sameee. I also love this kind of story!! Do you know the other titles that have similar plot like this??
Though many people dislike it because there is no character development esp at Tsukasa's sideㅡ i think that's what make it appealing to me? Tsukasa said himself that he never developed romantic feelings, esp since he began harboring such 'obsession' towards Shuu (with that fap material lol) hence its expected for him to be like that.
It's more confusing to think of how come that Shuu never thought of possibilities that Tsukasa might have recognized him. Shuu was full of confidence. That's it, his miscalculation. Anyway, it seems like Tsukasa also took in what his friend told to him. For me, that last panels where Tsukasa coming to Shuu's place are like a tip of that signal xD idk, hopefully it will be still continued in the other new volume.

Maybe I'm messed up in the head then, but I really loved this!
I liked how they both thought they were playing each other but really they were falling in love. I loved their chemistry. I also really loved the uncensored beauties. ;D And I guess I'm now a fan of the "we're meant for each other because we're both so messed up and it's all your fault" trope. XD
Stories with a bit more depth, even if it's twisted or psychological, engage me so much more than the Renta-quality fluff that's been permeating this site lately. Would love a sequel!
