If a person loses his past memory, will he still be the same person?
A disaster called "Nightmare" came to the world, and a mysterious continent appeared in the sky, announcing the existence of "gods" to mankind.
He met a man who was suspected of being his "ex" on that continent. In order to retrieve his memory, he embarked on a mysterious adventure. At the end of it all, he remembered his long-forgotten past and the entanglement between the two from life to death.
I know my heart, but my heart is not there.
I know what is in my heart, and I know it is not there.
Purpose: Love lasts forever
