I dont get this comment at all tbh but i guess he's inlove with both version of jooin. I think at first, he wasn't inlove with jooin he's just perhaps admire him as his "master" but as times goes by, his admiration began to change into "love" im sure there was one panel where he felt guilty bcs he felt more than just admiration to his "master" jooin im not sure what chapter it is though.

Is Cain actually in love with Jooin for who he is right now or is he in love with the Jooin he remembers in his past life ?
