People praise morally gray characters because they always take granted of green flag like Bongchun, he never sway, never ask for what he promised, he takes care of everything.
Many sympathize with scarred and traumatic characters because Bongchun never show weakness, he was strong yet soft, he born with nothing but he has big heart and kind nature. People didn't take a look deep at his figure because he always there, maybe for some he's boring, but for me he is the best character ever written.
Songap, this is how the universe reward you for all the hard times you endure.
