Revolution's manga / #Re-read(1)

(Volume 1) Only thing this volume had was "sex" Though it was still a good read I think? It seems I misunderstood about this manga. The first time i read it i thought there was only sex in it and second time too. But now after reading it for the 3rd time i noticed many things that i didn't before and now it felt more deep and the characters' feeling were really expressive if carefully observed. Gotta say it was better than what I was imagining this manga to be from before
