One Glimpse, Then Another

[Dual heroines + slow-burn romance + soul swap] One day, the carefree young master of the capital's foremost trading house and the frail, cautious Sixth Princess of the palace woke up in each other's bodies. The wild goose flying across the open sky became a bird in a cage, while the palace's caged beast found herself in the mortal world. Yuan Hong had thought that since she was here already, who wouldn't want to experience life as a princess firsthand? She couldn't outmaneuver the civil officials or generals, so surely she could simply play it safe and act the way the Sixth Princess would. But in the palace, where a single word could decide whether someone lived or died, she soon found herself walking on eggshells. The woman who had once done as she pleased learned to keep her sharp edges hidden and watch every step she took. At first, she thought she at least had to make sure she didn't hurt her. Later, she couldn't help wanting to protect her, to take her away, or at least to stand by her side. She wanted to face it all together. Xiao Mingshu had always thought that as long as she stayed in the palace and nothing went wrong, that was enough for her life. She learned music, chess, calligraphy, and painting, as well as poetry and literature. She was good at everything, but never exceptional. People in the imperial palace were indifferent, and her heart was just as calm and still. Nothing ever felt special. Until, without warning, she was thrust into the liveliest part of the capital. The bustle of the streets, the clamor of ordinary folk, their unrestrained laughter when they were happy and shouting when they were angry, all rushed straight at her. Flustered and overwhelmed, she gradually found herself longing for more. At first, she thought she just had to avoid making mistakes. Later, she couldn't help wanting to help her, to see her, to stand by her side, and to face the future together. (The author is not great at court politics, and the political intrigue is a little simplistic. Please don't overanalyze those parts.)
