Mr. Lu, Madam's Vest Is Too Cold.

A marriage between wealthy families, each seeking what they needed, locked Fan Xing, a 20-year-old genius vice-dean of the medical school, under a contract with the powerful leader of the Lu family, Lu Yuncheng. They originally agreed to be a "contract couple" not to interfere with each other, but Lu Yuncheng lost his reason little by little while getting along day and night. He watched her stun everyone in the variety show, watched her stay up all night in the laboratory, and even watched her calmly talk to the skeletons of the dead. He began to control her access control, cook late-night snacks with his own hands, and even use the group's legal department just because of her frown. President Leng Ao finally became a maniac about doting on his wife, and Lu Yuncheng just wanted to take out his heart and give her a sincere smile. However, in Fan Xing's world, besides scalpels and cold data, there seems to be a deeper and bottomless black hole hidden. Faced with Lu Yuncheng's overwhelming preference, she habitually chose to conceal and reserve, locking her sincerity in a steel safe. "Xing'er, what I want is never the fulfillment of the contract, but you." In this game that started with lies and contracts, who lost his heart first, and who lit the ever-lasting light for love in the darkness?
