"creepy step bro" has been so far a better option for him than the other grey hair piece of shit who treats him as a sex toy, gaslights him every chance he gets, trash talks him to other people, clearly never gives a shit about him except now because he is "jealous", that mentality that "he doesn't use his brain but has a crush on him" is bullshit because he does use his brain to manipulate him and abuse him emotionally and physically, he DOES NOT CARE.
"he actually does care about him" Yeah he only started caring about him when the spirit brother came into the picture, its not caring its being possessive. Had the brother not appeared Chanyoung wouldn't have cared about Hanjoo whatsoever. I do agree that at the cost of his social life Hanjoo gained a family however if anything the step brother is probably a swindler. He didnt explain what Hanjoo would have to sacrifice in order to gain a family which is manipulative, i can see that.
i think some people need to reread because the sunbae is a genuine guy, overly honest and showcases his emotions the way they are and he is actually a good guy (at least better than the black haired guy). it’s basically confirmed that the stepbro is a spirit and came to mc’s life because of a wish, BUT because of his powers and abilities it’s obvious he’s gonna distance mc from everyone and ofc he’s making bad things happen on purpose brah, he’s DEFINITELY the cause of why mc was ostracized from the rest of the people around him, IT WAS BECAUSE OF THE SPIRIT STEPBRO. the sunbae saw mc for his genuine self and actually does care about him although he prolly just doesn’t use his brain to think he actually has a crush on him and likes him more then he thinks.
