Liu Yi'an accidentally knocked herself unconscious on a piece of lab equipment. When she woke up, she found that she had transmigrated into the body of the frail younger sister of an idle official in Beichen.
She barely had a few peaceful days before her brother told her of a dangerous situation: while secretly investigating a natural disaster on imperial orders, he had been ambushed and poisoned.
She would need to pretend to be the sister of an unfamiliar man who had been assigned the investigation, and continue looking into the truth behind the disaster.
As an environmental protection officer, Liu Yi'an was well suited to investigate a natural disaster.
She saw this as an opportunity meant for her and was determined to find out what was really going on.
Who knew that the man she had just met would grow suspicious of her? His words sounded sweet, but as soon as her brother left, he hit her with the deluxe package of threats, surveillance, and tests.
Liu Yi'an: Nearly died.
When Xiao Yan put on an uncannily convincing performance as her brother, acting out a touching sibling reunion with her, she was just as good. She played along with her delicate act and gradually uncovered the truth.
Liu Yi'an thought they would be wasting their talents if they didn't join a theater troupe.
But as they spent day and night together, sharing hardships and facing danger side by side,
Liu Yi'an gradually discovered another side of Xiao Yan, one few people knew.
She learned about his past and soothed his pain,
using her fervent, sincere feelings to steady his uneasy heart and show him her passionate love.
Xiao Yan was born in the imperial palace and had seen his fill of rivalries, schemes, love, and hate.
His eyes had observed countless people, including himself, and had never once been wrong.
But that woman was the one exception. Her soul did not match her appearance:
resilient and sincere, she took everything in stride and stood by his side.
At first, he suspected something was wrong with her, but every piece of evidence proved his judgment mistaken.
He treated her sincerely, and at last she revealed an identity that shocked him, though he had long suspected it.
His mother's resentment and his father's sorrow had led him to swear never to indulge in love. It was the deadliest poison in the world.
But he could not stop himself from drawing closer to her, from thinking of her by name.
She was the antidote. With her, he no longer suffered.
Perhaps an oath means nothing if no god hears it.
Perhaps he could swear anew to spend a lifetime with just one person...
