dont forget the police officer my fav
Duna's Brother and his girlfriend also seem morally correct as well
Mihho is morally corrett? lol have you really read the manhwa?
(I will just copy and paste the comment of nims because she explained the situation much better than I could explain it)
He was so abusive with Doona during their relationship. He made her insecure and treated her like shit all the time, even after breaking up he continued to treat her badly and shamed her for her sexual preferences. Many times he acted like he was entitled to her like he owned her. Once Doona finally gave him a 2nd chance and saved him he immediately went back to his abusive behavior again. He is a shitty person and someone who always thought he was superior to everyone else which gave him the right to be rude to others, he dug his own grave on his professional field. Now when he finally had to man up and face the consequences of his actions (in his career) like the grown ass man he is, he goes to Doona instead, because he still believes he is entitled to her, he thinks that she OWES him something, kindness, care and whatever else which is SO SHAMELESS.
unpopular opinion i think minho and that one lesbian girl are probably the only vaguely morally correct characters in this entire webtoon
