They now know that since Michiru is a wildcat and not a lion, he's not biologically related to Shiou. It hasn't yet been revealed what this could mean, however it could imply that Michiru was adopted or perhaps the mother had an affair with someone. The characters are still figuring it out themselves.
okay but why is shiou avoiding michiru?? did I miss something?
and are they really brothers or not??
