I like this universe. Kongou and the Admiral aren't romantically involved but good friends. The Admiral is protective of the KanMusu because they're essentially his former wife's legacy and he wants to do right by her and not seeking to get into any of their pants. Nothing saying that he can't draw the protective card and keep others from approaching either, though.
I like artists that draw characters like people with different personalities and stories instead of a bunch of assorted moeblobs. This is one of the few good ones.
