Original, no cp direction. In the corrupt Kingdom of Iseland, Lei, who was an orphan, met Liyue, who was born in a royal family and fled to the slums. He was adopted by the shop owner Lance because of his outstanding talent. He learned knowledge by reading books and got clues from ancient historical books. He went to the north to find Lei's mother and discovered the truth about the Shattered Crystal and the so-called Stone Keeper. On the way, he met the elf girl Mysia who had fled to Iseland to work and Segris in the border town. And deep in the crack, apart from the glimmer of gems, there seems to be a crueler truth waiting to be revealed.
