I totally get why jaemin feels awkward around eunchae, she idolized him n put too much expectations on him but with pureum he doesn't have to pretend or put up appearances (she also disliked him in the beginning) n she's also unexpectedly affectionate to him at times
He just don't see her in a romantic way that's it no more no less. I get the lines he said and the philosophy and all, but he is not into her that way and she is just a gurl who he helped back then and helped her brother. pureum is another story though
