Yeah, even if I could look past the Ugly Bastard bit, the whole "Hey, this village just happens to have this perverted tradition and you can't say no" just ruins it.What I mean is that Masaru make things like defend her from bully girls, win a soccer match against mc, changing from wimpy guy to a more confident guy, etc... Are things that mc could do but Masaru do it and that's why he stole hey love. Oyama just touch her, do pervert thing to her and automatically she likes him, how could it possibly happen in real life specially between and old fat man and a young girl. But I have to admit that despite that Oyama has the hottest scenes like the two or three days that Oyama and Ryoka have in the temple.
Why I prefer Daisuke, Yasui and Masaru routes.
