first of all this manga is not fully translated and might not get translated anytime soon.
story - wimpy loser mc miraculously finds a gorgeous girl,both ends up living together in same room and generic romantic drama follows.
art- this manga is by my fav hentai mangaka so obviously it has quite a lot high quality ecchi scenes, the characters are beautifully drawn and the all the ecchi scenes are top class level.
Character - the main girl is a kinda tsunadre but not rude or mean or anything shes is average, our main guy is a pervert which at least is better than having
a dense mc. All other side characters are also in no way generic.
Enjoyment- boner? check, finished manga in a single sitting...intriguing? check
