When a restorer dedicated to safeguarding cultural heritage crosses paths with a sworn enemy who controls the world of capital, a shattered Song dynasty glass cup reveals a secret pact spanning a century.
At an auction in Haicheng, Sheng Wan, heiress to the Sheng family, enters a fierce bidding war with Ling Su, heir to the family’s longtime rivals, the Lings, to reclaim a Song dynasty glass cup that symbolizes her family’s cultural legacy. But when the cup unexpectedly shatters, it reveals mysterious symbols hidden inside, pointing to a truth both families had forgotten: a “Peace Pact of the Founders,” sealed by their ancestors a century ago.
To solve the mystery, the two enemies, once as irreconcilable as fire and water, are forced to join forces. As they pursue the truth, they are hunted by an unknown force and discover that the enemy threatening their families is far closer and more ruthless than they imagined. When Sheng Wan’s most trusted uncle reveals his true, vicious nature, and Ling Su is gravely injured protecting her, the generations-old hatred between them begins to melt away under the test of life and death.
At last, atop the Glass Pagoda, a symbol of the city’s origins, they find the pact’s ultimate answer. It is not the key to some hidden fortune, as they expected, but a marriage contract requiring the two families to unite their bloodlines and jointly protect their cultural heritage, along with a grand vision of shared prosperity.
“This isn’t the end,” he says, slipping a ring engraved with both their surnames onto her finger. “It’s a new pact between us.”
