Most reasons are coz he was the source of all yusung's messed up future coz taewon decided to stick with mr. Kim and now mr.kim has him hostage. Top reason is how Taewon decided he'll treat Yusung so bad that Yusung will quit all on his own despite the fact that Yusung needed that job and Taewon knowingly stepping on Yusung's feelings for him. Among the other guys, Taewon was only special coz Yusung liked him but he's also the guy who treated him worse
Im not too mad about taewon being the end game, in the first place i already got the hunch and as the story progress it's pretty much predictable already, so im fine with him being the ml, that's why i really don't understand why everyone's malding over it, i guess it's different for everyone, im not too invested on the romance anyway, still, the plot is good and it's progressing nicely
