Two half-sisters, carrying the grudges of their past lives, transmigrate together.
The elder sister chooses to stay quiet, adapt to this new world, embrace its rules, and start over. The younger sister, however, chooses to use her modern knowledge to change her life.
The legitimate daughter is wise, courteous, gentle, and gracious; the concubine-born daughter is talented, clever, and kind. Between legitimate and concubine-born status, between arranged marriages and love, and between the grudges of their past and present lives, the two are destined to clash. Like two blossoms on one stem, they cannot both flourish.
Some things cannot be changed simply by transmigrating, and some love cannot be won simply by transmigrating. Transmigration is only a matter of living on in a different time and place.
