What a fucking horrible and totally pathetic story, first of all the plot barely moved at all on it's firsts 12-15 chapters, It was extremely slow and made me yawn a lot of times, second, suddenly, a random day, a common day, this poor bastard hikikomori has a extremely beautiful big-titted woman in his house out of nowhere and 1 month later she fucks with this weird jacko-freak (not including the fact that he has a monster cock) and pleases her until the climax. Is just unacceptable the fact that he is just a normal guy 6 years later after being victim of his own imprisonment on the room for 15 years. No... just no.
No, really, what a mishmash of bullshit. The ending was horrible as well. Although I will admit that it had a lot of potential on it's first 2 chapters, but whatever, I had to see how this was going to end.
I have to agree on the fact that the ending was bad, but I found the story to be pretty good till the end. Also, becoming a normal guy 6 years later is completely reasonable. The only reason he was able to sustain his life in his room was because he was being supported by his father and mother-in-law. After being only given a enough money to live, he has to learn exactly how to not waste money and only buy the necessities, which he didn't do at all in the beginning and thus got a taste of starvation. After that, everything else comes quite naturally, that is: the need for extra money, getting a job, acquiring a social life, creating relationships with other people, and so on and so forth. Of course he can always manage to get stuck on this path, but 6 years is more than enough time to do this. Now as for how he managed to get his own restaurant and a family of his own, that was probably something along the lines of working at a restaurant, becoming liked by either the owner or his daughter, marry the daughter either through her directly or through her father, and finally inheriting the restaurant - not necessarily in this order... I still didn't like the ending though. It was much too unfair for the woman. I remember bawling my eyes out as I ranted about how it should have gone, but that was quite a long time ago...
