The relationship between South Africa Wan and Chen Su can only be described as "love and kill each other".
Family, mission, misunderstandings, the sister who appeared out of thin air, the catastrophe of the fairy world... All of these have become barriers between us that can never be eliminated. Instead, they have become deeper and deeper and can no longer be crossed. You completed my mission for me and sacrificed your life to protect the peace of the world and me, but left me alone in this world to guard your memory and these two children.
If I had known that you and I were destined to be together, I would rather not have this fate and protect you.
