Zhou Shengchen, the young prince of Nanchen, who became famous at a young age and had made great military achievements, was determined to be loyal to the country all his life. His rigorous style and humility were praised by the world. The only daughter of the famous family, Shiyi, was betrothed to the future crown princess at birth. Because she was a family friend of the royal palace, she was sent to the palace by her elders to learn martial arts. Shiyi was kind, lovely, lively and intelligent, and was deeply loved by everyone in the palace. She made rapid progress in her martial arts and was the happy fruit of the palace. In the little things they did together, Shiyi admired Zhou Shengchen's lofty ambitions and elegant character, and fell in love with the general unknowingly. Whether waiting for good news in the palace or fighting side by side with Zhou Shengchen, Shiyi was Zhou Shengchen's strongest backing and warmest support. The relationship between the two quickly heated up, but they still started from love and stopped at etiquette. The border is in danger again, and Zhou Shengchen has no choice but to lead the troops to fight, while Jin Shiyi has to take on the responsibility of marrying the prince for the family's reputation. Zhou Shengchen, who fought bravely against the enemy, was murdered by a traitor and died after leaving only his last words to Jin Shiyi. Jin Shiyi was so grief-stricken that he jumped off the city wall and died for love.
