Hmmm so does jisuh have feelings for him but wants to get him back for what he did, or does he feel nothing at all and It's all just a trick?

He is confused. He had fallen in love with Heejae but then discovered that he had been betrayed and played with all the time. Then, the love turned to hate.
But as he keeps on spending time with Heejae and seeing his unguarded, honest, and cute sides up close, he started to understand Heejae better and feel that the hatred is alleviating and that there is a risk of his affection returning.
But he doesn't want that because of how hurt he felt and is still feeling.
In the end, Jisuh is simply not as insensitive and cruel as Heejae. It is not on his nature to hurt others and not feel anything. He is doing it only because it is a special situation and as so it is easier for him to give up and let go so he has to fight against that.
Why the fuck is haebom so cute and pure i almost can't handle it (▰˘◡˘▰)
