Because this chapter made you realize Haeyul is deadset treating Jaewon as Hesung's stand in since Day-1 and never try to see Jaewon as who he is despite them spending all those time together.
Dojoon on the other hand quickly disillusioned as Jaewon has completely different (crazy) personality and gradually fell for who he is, which makes Haeyul more pathetic in contrast.

I knew it! White haired guy wants a stand in, he's delusional, this is why white haired guy will never be the ML, what a loser
