Rowen's relationships seem to be fairly friendly in the anime. In the drama CD he seems aloof and a little cold. Understandably since he doesn't seem to interact with people his own age much. However, because I'm more familiar with the anime, my thoughts will be mostly based on that. Oh and my head canons because I've had this fandom floating around for years. Years. Basically, I think Rowen's a great guy (and look at how adorable he is)! As if that isn't terribly obvious. In general, I think Rowen probably gets along well with most people he meets and interacts well. I think he's mature enough to understand that sometimes you really just need to tolerate people.
