Yan Qi has never known who his parents are since he can remember. He was adopted as his son by the King of Hell, Yan Yi. Years of training have made him Yan Yi's sharpest knife. In the eyes of many people, he is considered a superior Alpha, but his true identity is only known to him and Yan Yi.
Yu An is the son of Yu Feng, the God of Angels. He is an arrogant and sinister Alpha. There are many Omegas who always flock to him, but he can walk through thousands of flowers without a single leaf touching him.
The two met during a mission, but since then they have stopped communicating with each other.
Yu An has always been obsessed with Yan Qi, and would always secretly go to the mortal world to look for Yan Qi, but never found him. He did not see him until the five-thousand-year appointment between hell and heaven. From then on, angels were no longer angels, but devils.
