@Jarupat01, and? people who become soilder or knight cant have trauma and nightmares? they have to be strong all the time, and by having fears and mental trauma is a sin? they are human being and not a robot. and every human is different.
If you look closely, uriel had much improvement over these last two years, he pretty much able to function and overcome his trauma. He is a survivor and a strong person. If he is such a weak will person he pretty much still stuck in his room, and maybe killed himself from all the stress and trauma.
Is selfcare and selflove a selfish thing? For the past two years, he had been focusing to improve himself despite having a disable arm. Whats wrong with that?
The reason why people like Uriel because he is a genuine person (and no he didnt call aquila's mother a witch, it was other people gossiping about the prince. He defended him and respect him as a fellow swordsman and praise him as the revered swordsman. He sympatize with aquila because he also had been ostrasized by people around him- being the kid that kill his mother). He is kind and honest (compared to his family and people around him). He's pretty much your common noble and honest knight and, he is weak and strong like a normal human would be.
He is not an OP character, he is a human character. His dreams is he want to be a simple knight to protect his family and aquila pretty much destroyed it ( for what ever the reason is). And now even when Lamia pushed him to be the duke, he accept it , and carry his responsibility with most of his capability. He pretty much move on with his life, and try to make the best of it. As for now, maybe thats the reason why people like uriel.
