Shen Chunying, the second young miss of the Marquis's manor, spent her past life single-mindedly chasing the empress's position and married into the East Palace, only to end up with a heart full of regrets. Reborn back to the time of marriage discussions, she suddenly wakes up, lets go of her obsession with power and influence, and willingly accepts her betrothal to Ruiwang, Pei Hengyu. The elders at home have always favored the eldest sister; facing the unfair treatment of her original family, as well as the various promises later thrown out by the crown prince, Shen Chunying remains completely unmoved. At first, Ruiwang only wanted to be a couple respecting each other like guests with her, but the two gradually developed genuine affection for each other through daily companionship. Shen Chunying resolves to cut off past entanglements, takes the initiative to request an early wedding, and subsequently follows Ruiwang far away to his fief in Sichuan.
