They are. It's mentioned in a phone call from Michiru's Mom. The dad is part wildcat, part lion.
I smh missed that reading part lol, thank youuu, I was so confused but you clarified it for me!!! Your a life saviour!!!
No problem! It's actually the one thing I don't really like about this one. I'm not into incest stories and it's full of brother complex... but yes, they're full blooded brothers. I'd prefer either less bro complex or for them to not be blood relations (just my personal taste).
Actually Shiou and Michiru are related by blood or not?!??? I'm really confused but the story is good
