The Cold Prince and His Buddhist Princess

[Sweet text between male and female protagonists doting on each other+daily life after marriage+traditional ancient sayings+HE] [His Royal Highness the King of Yan is rumored to be cold and cruel × the second young lady of the Song Dynasty who is intelligent and Buddhist] Song Huiyin, the second daughter of the Song family, was able to eat and sleep. She just wanted to live a happy life as a Buddhist. When she married Shen Yanan, she thought that the two of them would spend their lives respectfully treating each other as guests. After getting married, she discovered that her husband was different from what she had heard, and her clumsy love grew wildly. Shen Yan'an was the second prince of the current dynasty. The emperor personally named him King Yan. He went to the battlefield with Marquis Ning'an at the age of thirteen. At the end of every battle, he would see Marquis Ning'an take out a crooked embroidered handkerchief from his arms and talk about his naughty granddaughter. Over time, it entered his heart and penetrated countless dreams of the frontier when he was young. Without expecting a marriage edict, she actually became his princess. When they met for the first time, she stood under the plum tree and saluted him with a smile. King Yan, who had always been calm and self-possessed, was so nervous that he didn't know what to do and had to pretend to be calm and hurried away. I am working hard every step of the way, just hoping to protect her from being happy and worry-free throughout her life.
