The Fairy's System

After a great battle, he fell into the mortal world and became an ordinary human through and through. He lost his memories and his spiritual power...

Sometimes, she even tipped him off and broke its rules. She could change anything for his sake... She hoped that one day, she could walk hand in hand with him along the banks of the Lotus Pond...
