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.My favorite is the Oyama route, I really like how slowly Ryoka falls in love with him
