Racial bond + two-way redemption in a fantasy background. In a different world of immortality and eternal silence, the human race coexists with other races, but possessing superpowers can only be used by the human race through a contract. This is a sorrow engraved in the bones and blood, and it is also the original sin of allowing others to bully you. His destiny is to sign a contract and become a vassal and plaything of the human race, experiencing the desolation of the world. The truth emerged, all the shackles were broken, and they broke free from the arrangement of fate. It had nothing to do with race or contract, only the deep love and bond that transcended all were left. From then on, they depended on each other for life and death, and stayed together year after year.
▷ There is no warmth in eternal life. Fortunately, we meet again. You are my salvation.
▷ The contract is the matchmaker, the redemption is the heart, and you are the only one who will live forever.
