Let's not forget Dan has always lived with an abusive and violent atmosphere, he's always expecting hurt, not that it's a good thing, and those loan sharks + the doctor who tried to rape him hurt him without him getting a reward for it or wtv, and Joo helped Dan financially while hurting him, so Dan took him as a good person BC he atleast helps him out as the result of Joo having violent sex with him, and Joo never physically hurt Dan, but has humiliated him and ruined his already messed up mentality, so moral of all my yap is that 'Dan takes Joo as a good person because he helps him although hurting him at the same time'
Dan is so cringe for always thinking that ass hole is a good person. He’s so pathetic
