I kinda feel the same, hmm... It seems that Kudou-san coming to terms with his sexuality was only sorta shown though his actions. It would have been nice for them to have some more deep conversations. Kudou-san has a lot that he would benefit from talking about aaaand we don't really know much about Satou-san either, haha
Yeah i saw some comments calling Satou san cold and cunning. I think That's only because the story focuses on sex more than actual character development which sucks because the art is beautiful and the characters had potential to actually move us but fell short. Sucks 4 me because I've been searching for a new good manga
Everything is great except I wish they had personalities. Especially the Kudou-san. A heart to heart about him accepting his sexuality. A climax of some sort would have made this perfect
