SAN He is loyal to his love. He has been waiting for the reincarnation of his lost love, Wad, all his life.

But when night falls, he will be tortured repeatedly by the power of the five-color stone. If he cannot find Wad within the current century and lift the curse of the five-color stone, he will inevitably die tragically.

Before the power of the stone becomes his eternal curse, towards the end of the last year of the present century, he meets VEE, a flirtatious, handsome and charming young man who seems to have a close connection with his life.

SAN was shocked when he first saw VEE, but this unrelated boy was actually his beloved WAD, whom he had been waiting for nearly a century.
