To be fair, Jaekyung has been nothing but consistent in his behavior and upfront about the situation and what he wants and had proven he does things to his personal benefit. Dan on the other hand is the one romanticizing things and reading into things and getting his hopes up. Even though the ex lover seems bitter... He's kinda not wrong.
The whole past life "I was a dog/wolf" arc is so weird and honestly crazy. And it wasn't even a plot twist thing it was written in from the start.
