Su Qinghan married into Gu Mansion three months ago. Her husband Gu Yanci was as cold as ice, and there was an undercurrent in the manor. In an accident, she discovered that her mother-in-law was colluding with the charlatan Feng Sanshou to seize the Gu family's ancestral property, which also involved the secret of the Gu family's ancestral tomb.
The ancient tomb holds the key to the rise and fall of the Gu family, and it also attracts the covetousness of the evil magician Mo Xie, who attempts to use the power of the ancient tomb to practice evil arts. At the same time, Liu Rumei, who had been suppressed by the Gu family, returned with hatred and vowed to destroy the Gu family.
Su Qinghan uses aloofness as his armor and uses his wits to navigate between house fights and the crisis in the ancient tomb. Gu Yanci, who is as cold as ice, always shows up when she is in danger, and even secretly gnaws honey cakes when no one is around - it turns out that there is a secret of sweetness hidden under the iceberg. The two join hands to fight against the traitors in the house, thwart the evil master's plot, defeat the revenge plot, and find a way out amidst the frost and snow in the tomb and the smoke of the house.
