So blonde and green eyed twinks are the reincarnation vessels of all regas'?

Basically cause at the staring that what we saw

Wait is that true? I must have missed it if they said it. I just thought blond hair green eyed twinks were the dukes type and that they arent special but everyone thinks they are because the duke likes them

From what I remember, no. It just so happens that the previous king's regas and Abel are both blonde with green eyes.

Spoiler ahead:

We learn later that the first few generations of Regas were all strong, able-bodied types like the original Abel. There's no indication of whether they were blonde or green-eyed.

I'm just saying cause I remember in chapter 1 we saw the first regas was a blonde twink so I'm not sure if that's the actual case

Nope. Truyde likes blonde and green eyed twinks thats why a lot of regas are blonde and green eyed twinks. Everyone of the noble family kinda knows that Truyde is the one who holds the real power in the palace, ever since the previous king's reign, thats why everyone is trying to cater to his taste. And well, his family curse is kind of an open secret.

Yh it show that the previous king regard was like the original abel
