You know dear, I actually think Ryo is a girly man in terms of emotions in a relationship. I canso picture him being the girly one in the couple,I mean not the gentleman acts, but the talks. Just him being so shy in front of girls makes me think he can act and talk girly too. Hell! We already heard him talk girly more than once! Even if only for tv shows!

I like how you said Ryo was teached something from witnessing Maru and Ueda's relationship; yes the sweet relationship.
But Marus is being mature. He knows, lol...won't say much.
