@Kampfarsch Sorry for dragging up an old comment (just discovered the series and am binging it), but if you're talking about his voice, Nanami came up with the excuse previously that "Kaori" has a complex about her "deep" voice to explain why "she" wasn't talking much; in Japanese media, you often have those female characters that sound like chipmunks with how high pitched their voices are, so if that's the expectation in this series, he could straddle the line between a soprano and contralto and sound like Rambo in comparison.
