Happy ending!
@nomadicengi as far as Jun soul goes, I am pretty sure Jun/Louise soul went back after Louise passed away from old age. At least that's what it seems like when the goddess said she could return Louise/Jun anytime to Jun's world.
@Tcof because our ex said something along the lines of liking our hair style or loving our hair when it is long so we want to change it up and not let it remind us about them especially if the ex is the one that broke things off or caused the heartbreak.
