- The Lu Group encountered a business crisis, and Su Qingyan helped Lin Wanyi resolve the big trouble with the help of key information (or ancestral skills/connections) that she accidentally learned.
- Lin Wanyi was originally dissatisfied with her son Lu Tingyuan's girlfriend Bai Ruoxi (she thought she was vain and unhelpful to the family), so she took the opportunity to force Lu Tingyuan and Su Qingyan to sign a one-year marriage contract on the grounds of "repaying gratitude" and "family interests".
- Lu Tingyuan was deeply in love with Bai Ruoxi, and was extremely repulsive to this "trading marriage". He regarded Su Qingyan as a wannabe who was greedy for wealth. After the marriage, he had an indifferent attitude and lived in separate rooms.
