Yes he is not bad as people made him in comment section, he meant to be bratty and spoiled if we see their kids story , it's more good that only omega knows his true side and both of them play part of happy couple in front of other , Shaia is caring and observing like Juda i like how he has his both parents behaviour. It makes it more interesting as for his other brother he is quite and calm type.
Now that you mention it, he really did pick up all the bad traits of his parents lol. Daato's abrasive and sarcastic speech and Juda's arrogance and ego.
Yes he is just like his parents may be that's what makes him an interesting character for me .
I love Shaia’s personality! He was raised lovingly and spoiled so of course he was gonna grow up to be cheeky and a little mean. This is probably my favorite kind of seme. Juda was nice by being possessive and my favorite in this verse. But if Shaia is a little mean on top of that then it checks all the boxes for me. I love how he’s always smiling and plays it nice in front of the elders and it’s actually spoiled rotten and sharp when he’s alone. Let’s gooooooo. I hope Hasumi doesn’t change his personality too much and keeps his mean streak even when he falls in love with this omega.
