"Even after knowing he loves someone else" dawg because that's what people fucking do? It's like the most normal thing to do when you're in love. If you're the type to simply give up then that's on you. Jooin advising Cain to not get involved in that mess was not him saying gtfo bruh It's what yall wanna hear but Jooin was literally fine with Cain being around. He was grateful for his presence too
Yeah i didn't deny that tho?? You the one who said he should've stopped pursuing him when that's literally just common sense when somebody's in love. And no what Jooin said was meant in a "i dont wanna bother you with my life way" not the "gtfo i dont want you around" way bruh it's so easy to understand like

Jooin will never be the bad guy y'all want him to be lol. He never kept Cain in dark. It's not his fault that Cain was ready to lick the floor he walks on. Cain was well aware he liked someone else, but that cuck still persisted (Bro probably thought he was the main character who would change MC's mind IJBOLL). He isn't the nice guy no matter how much y'all sugarcoat his personality, he took advantage of Jooin when Jooin was most vulnerable, trying to emotionally manipulate him. Even after repeatedly being treated as the second option, he stayed back like a loser with no self respect whatsoever
(MAJOR side character vibe). So yea it WASN'T JOOIN'S FAULT. It was never his fault that two guys were crazily in love w him and he chose the one HE loves. Y'all can stomp your head on wall, all you want. JOOIN WILL NEVER BE THE BAD GUY.
