i think the artist did their best (novel spoiler)

the novel was really long, it was 100/300+ ch i dont remember but this particular part of his growing back wings was heartbreaking.
IIRC
it was for days, his wings didnt grow entirely, but it goes from a baby small wing to an adult wing. The was it described felt painful I thought MC couldnt make it bro

After he wakes up and healed a little, he went outside cause he have to see his vassals. they were kneeling outside for days, they didnt eat/move cause they cant bear the thought of their king suffering
