Peach blossom debt
(Book)

"All predestined affinities are merely debts to be repaid... In his mortal life, Song Yao ate an elixir pill that dropped from the heavens by accident, and thus began his life as an immortal. After millennia of living in idleness, the Jade Emperor orders Song Yao back to the mortal plane. His task is seemingly simple: to oversee the love trial between two immortal lords. Only when he bids his old friend Hengwen Qingjun farewell at the heavenly gates is he told of his true role on the mortal plane: to steal away the heart of one of the lords, Tianshu Xingjun. Falling from the skies with no way back, Song Yao can only wonder, who's really being put on trial here?" --,Back cover.
