I don't remember yuan ever disrespecting him though? If anything he seemed bother about what he went through with the pictures.
that was really a short moment.
the MC took revenge for Jiang so there is no I don't think the MC doesn't care or wasn't respected about him, he did care but there is nothing he can do after the guy was dead. and has much I feel pity for him, he still chooses to die by taking drugs with alcohol. you can blame the other characters for this, but he still chooses to do it.
While I am happy for the two main characters, I still feel horrible about the jiang mu (before his soul was replaced) i hoped that by the end of the webtoon he would be given justice or at least remembered. the poor guys whole life was a mess - had dirty pictures of him online, was poor, and was a sex friend to huo yi and was never treated with care or respect i hope in future he is more respected by bith of them, because without him the actor could not have been reincarnated and huo yi maybye would have died from depression and treat the poor boy with hatred.
