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

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.

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.

And LMAOOO THE PANICKED "YOUR MAJESTYYYY!!?? " BEAHHAHHAHAHA I keep laughing out loud this entire manhwa

I just loved how they pointed out that "Your Majesty" is literally the smartest entity in the room at any time (even if his commanders are one 3 body problem away from sharing the communal brain cell); and next thing you know that the one that devised some intricate plan in the making like chekov's firing squad is now VERY bothered by Sir Ashler handsomeness (of all things).
