Probably I can only say that he is truly inlove with aryka and truly move on from yeon's death is if that moment when aryka need to leave him and he will bravely accept it and will continue living while being thankful that he met someone like aryka at his lowest point in his life that he is his light.And being hopeful that someday when they met again he could say to aryka that he live his life because aryka teach him that life is worth living and love will not drag you to a pit of darkness but will be your guiding hand to continue living the best out of your life. Just my wild thoughts cause no! If he say he love him now I will not believe it yet.
