Its been a while since ive read this ut im also pretty far ahead
So without spoiling anything. i believe the writer orginally intended this to be a gag manhua so they did retcon things left n right. However, it seems the writing is far more consistent later on in the story. just my own...
I can see that being a gift for trauma, and also granting the ability to move on and forgive as a byproduct
But i think this is more of an immortal's philosophy rather than human so i see your point
its definitely gotta be that guy who didnt get into the communal bath with every1 else. He even had a big body guard type friend who vouched for his "package" size lol
As a side note, pretty sure that guy/prince is going to turn out to be a girl/princess in disguise
