Why i can't hate Soo Won at all (╯°Д °)╯╧╧

Right?? Like, I could've hated him more if he was a douchebag king but no! He's not! He's rational, strong and unbelievably intelligent.
Maybe he has a terminal disease though? He gonna die soon because Yona and him can't coexist

And unbelievably kindddd (╯°Д °)╯╧╧ God, if it's true that would be tragic.. I mean they both lost their father, can we make it even?? Soo Won don't deserve that kind of ending
