About His Unforgettable Ex
Sue accidentally bound herself to an Immortal System, but each death consumed a massive amount of energy. She loved Ray deeply and willingly took risks for him time and again. However, Ray, desensitized by her immortality, grew indifferent to her deaths—even asking Sue to die in place of his cherished first love, who had received death threats. Heartbroken, Sue agreed, but Ray never knew this was her final chance at life. It wasn't until Sues life signals vanished completely that Ray was consumed by regret.
