Su Wanwan, the daughter of the Su Group, lives up to her name, is gentle and smart, has a pair of almond-shaped eyes full of smiles, and has a fresh flavor of life. She is good at baking and arranging flowers, and is recognized in the circle as the "little sun". In an accident, she ran into the arms of Gu Yanshen, the president of the Gu family.
Gu Yanshen, a top boss in the business world, has a stunning appearance and an outstanding IQ, but he is dark and cold in his bones. He never believed in the warmth of the world until Su Wanwan broke through his layers of disguise like a soft little sugar ball.
He took every step to draw her into his arms. He thought it was just a show of love, but he fell completely under the spell of her smile.
Childhood sweetheart Lin Zimo, the male lead, appears to be as gentle as jade, but is actually very ambitious. He is jealous of Gu Yanshen's power, and covets Su Wanwan's family background and sincerity. He secretly joins forces with the vain and jealous female lead Bai Weiwei. One of them pretends to be good to sow discord, and the other hides a murderous intention to seize the family property, pushing Su Wanwan into danger.
When the conspiracy was revealed, Gu Yanshen protected Su Wanwan behind him, with a cold look in his eyes: "You can't afford to touch my people."
The sinister CEO turns into a wife-protecting maniac for love, and the playful wife joins hands to break the situation. In this contest that is mixed with conspiracy and affection, who will have the last laugh?
