I'll say it in a few words. If Yamane Ayano's serie Finder is such a beloved one and it's all about rape (without funny stuff or an actual plot) how can peolpe say things like this one is horrible? This manga is simple, funny, cute and sexy. Do Morinaga rapes Souichi? Well, if you're raping someone you don't prepare them and try them to feel good. But if you want to consider it as raping and Morinaga a serial rapist (WHAT THE BLOODY F*CK?), ok go ahead, but you'll have to admit that it was only one time. Blackmail? HECK NO. How can you blackmail ANYBODY with "I'll go away if you don't do it with me" If it were me I would just laughed at him and kicked him 'till dead...
But well. YOU that you're interested in reading this beautiful manga, do it, it's great. I'm a comedy lover, I know what I say. If you're looking for some really realistic or melodramatic stuff this isn't for you, but if you're on the search of a good, funny, sexy and with-a-good-plot manga this is a MUST.
PS: The comment below mine... I have read the mangas she recommends...they're average, if you want quality manga don't read them, they're good for just...spending time reading a not-bad-manga but nothing memorable. Do you want good comedy? Read Natsume Isaku, Naono Bohra (hehehe, some of her works are kind of bizarre...but they're fun) Tomoe Fumi, Nekota Yonezou, Abe Akane, Madarame Hiro, even Nakamura Shungiku, Honto Yajuu etc, they are all great mangakas and mangas. Do you want drama? Yoneda Kou, Hidaka Shoko, Yugi Yamada, Sakuraga Mei, UnderGround Hotel, Totally Captivated,Kyuuso wa Cheese no Yume o Miru, Haru wo Daite Ita blablabla.
