Mingruo and Xiao Chen

Jun Chenyue was once the exalted Heavenly Princess of the Divine Realm. After a sudden fall from grace, she became a distant cousin of the Su family in Jingcheng, and even acquired a little tagalong who followed her everywhere.

Who knew the tagalong had another identity? He transformed into a great demon king, taking her across the Three Realms and back to the Divine Realm.
