Rivals + Marriage First, Love Later + Loyal Dog + Double Cleanliness + HE Sunny, cheerful, obedient and loyal dog attack VS a fishing-type beauty who is cold on the outside and hot on the inside In the 20th year of Yu De's reign, a quack magician calculated that Murong Ci, King of Shangrui, was facing a great calamity in his fate. He needed to combine with Jiang Yangu, the noble prince of Prince An, to resolve this calamity. In order to protect Rong Ci, Emperor Yu De decreed that the two of them should get married. Since childhood, the two of them have been rivals that if you beat me once, I will beat you twice. Jiang Yangu originally thought that after getting married, Murong Ci would not be very kind to him, and would just be like him, waiting for this ridiculous marriage to be annulled, but to his surprise, after getting married, his former nemesis was not as he imagined, but was extremely kind to him, and he also lost his heart inexplicably and was unwilling to let go. How can someone be a bitter rival for more than ten years, but they just want to get closer but have no excuse, and they love without knowing it.
