Su Niannian, a two-dimensional illustrator who looks cute on the outside, is actually a bitch on the inside. To fulfill Grandma's wish, she signed a one-year contract marriage with Lu Yanting, the president of the Lu Group, who was forced to marry. He has a cold and venomous tongue, and is possessive but refuses to admit it; she is hard-spoken and soft-hearted, and will avenge her on the spot. From fighting each other and living together to secretly having feelings for each other, from being a contracted couple to treating each other sincerely. When the venomous boss starts searching on Baidu for "How to make my wife angry", when a clever painter secretly draws him into a Q-version emoticon package - in this marriage that started with a transaction, who surrenders first in heartbeat? Marriage first, love later, sweetness mixed with resentment, resentment mixed with pampering, a long heartbeat about healing and growth.
