Xiaochan married Lu Yan because he had eyes that looked exactly like Ayan's.
Those eyes were clean and bright, and they shouldn't be on Lu Fan's annoying face.
Lu Fan is always angry with her.
She wanted to dig out those eyes and soak them in a potion from the Western Regions, but unfortunately she couldn't save enough money to buy the potion.
Later she finally saved enough.
Intention: Unswerving determination.
