Based on context clues he runs to Cain at the end of the chapter kind of blushing and he hung up on Yahwi when he called leaving him alone saying he’s no longer doing anything in impulse so either he’s choosing Cain or this is meant to mislead us but I don’t think so. He also said he wants to embrace Cain like he did to him all this time and other stuff

No literally like I feel like it would be so cruel if the author purposefully did this to mislead us I would honestly be super upset because even now yahwi is shown to have not changed at all in his behavior and jooin knows this so if the author makes him choose yahwi that just defeats the whole purpose. Cain is clearly the better option and I’ve always stood by that.
Spoilers for the new chapter but DOES ANYONE ELSE THINK THIS MEANS JOOIN FINALLY CHOSE SOMEONE?
