Nanami is a very wise and reserved kind of man, often appearing so calm and indifferent that he comes off as stoic and aloof, even though he deeply cares about his loved one and is undoubtedly willing to sacrifice everything for them. He's very loyal, sometimes jealous but doesn't show it, husband material, the greenest green flag, reliable and intelligent. He never lets his emotions show, but sometime he lets them slip, only in front of his lover.
