I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I'm really not sure what the author's trying to do here. It doesn't even make sense: if Asakawa trusts "a woman's intuition," then okay, Mai thought Ryuji was a gentle and innocent person. But Shizu, another woman, couldn't stand to be around Ryuji. Why trust Mai's intuition over his own wife's?
