A genius transmigrates and wakes up as a princess, only to be raised as a prince. At fifteen, she discovers she is merely a stand-in and returns to the chancellor’s residence, where she takes her place as a concubine-born daughter. But who can tell truth from lies, or right from wrong? As the genius navigates court politics and the deadly intrigues of the inner household, who will ultimately win her heart? The threads of fate have long bound the two of them together. Is she here to watch the show, or to protect herself? Her seventeen-year plan is finally laid bare, but who is truly the one moving the pieces? A delicate red-bean die, a heart full of cleverness, and a pair of slender hands that can toy with everything. With the four seas as home, old friends forget one another; through thick and thin, my beloved returns from a distant land.
