Shu Yi, the eldest princess of the imperial dynasty, was forced to marry the Northern Yi, and developed a secret love for Liu Tianyou, the imperial doctor who treated her heart disease. She believed the emperor's brother's promise that he would "come back in two years" to marry far away, but what she received when she returned was a last-minute letter - Liu Tianyou had been sentenced to death. She found the tomb, carved "Tomb of Liu Tianyou's Beloved Wife", and then slept beside it. A deep love that transcended identities was finally crushed into dust by the words "for your own good".
Purpose: The story uses the forbidden love between the princess and the royal doctor to explore three propositions: Can people be their true selves under the shackles of identity? Is making a choice for others in the name of love fulfilling or violent? When the righteousness of the family and the country overwhelms individual affection, is the love of a small person a futile resistance? The Long Night is not young, what we see is not only love, but also the right to choose that is deprived of under the shadow of power.
