Chen Ninghai unexpectedly arrived in Teyvat and became the Spear Saint, a Demon God, 3,500 years ago. Several hundred years before the Khaenri'ah war broke out, he met Raiden Makoto, and the two fell in love. But before he could propose, the Khaenri'ah war erupted, and both of them perished there without exception. However, Chen Ninghai used his power to preserve their consciousness and bodies, and together they fell into a deep slumber.
Five hundred years later, the two awoke together in Liyue. Puzzled by the new world, they began a new life.
Too sweet without a hint of knives.
