The luckiest thing in Su Ruan's life was that from her school uniform to her wedding dress, she was pampered by Gu Yanshen and became a princess. She fell in love at a young age and stayed with her for many years. He was the decisive and aggressive Mr. Gu in the business world, but he was her exclusive loyal dog, giving her all his tenderness and preference. From the sweet love to the safe pregnancy, Gu Yanshen held her in the palm of his hand and took great care of her, wishing he could bear all the hardships for her; he was very careful during the ten-month pregnancy, and once she gave birth to a narrow escape, he stood outside the delivery room, not as panicked as that omnipotent man. During the thirty days of confinement, he was a super daddy who never left her. He loved her and tolerated her. He lived like a knight guarding a treasure, only daring to protect it but not daring to touch it. Everyone was surrounding the soft and lovely daughter Gu Nianruan, but the one who was at the forefront of his eyes and heart was always his eldest baby Su Ruan. Finally, when she was out of confinement, the longing and attachment that had been suppressed for a whole year completely exploded. He gave her the ultimate sense of security, and she returned his tenderness. From the two of them relying on each other to the happy marriage of three, she has been his only sweetheart in the world for the rest of his life.
