Fifteen-year-old Su Nianci never thought that a sudden car accident would turn her from a delicate flower in the greenhouse to a helpless orphan. Her parents' entrustment before their death pushed her towards a man she had only met once at a family gathering - Liu Yichu. This man, who is fifteen years older than her, is a low-key but very important upstart in the business world. He is surrounded by aloofness and avoids strangers. It is said that he has sharp methods and deep thoughts, and is a being that even his elders must respect.
When she first arrived at the Liu family's mansion, Su Nianci was full of fear and caution. She thought that what awaited her would be the care of someone else, but she didn't expect that Liu Yichu gave her the most appropriate protection. He would remember her little habit of not eating coriander, he would silently guard the door when she had nightmares late at night, and he would calmly solve the problem when someone bullied her at school, but he would never show half of his business sharpness in front of her.
Under the protection of Liu Yichu, Su Nianci gradually emerged from the gloom, growing from a timid and sensitive girl to a bright and tough person. However, that dependence gradually deteriorated, and feelings quietly developed that even she did not dare to admit. But Liu Yichu always maintained a restrained distance as a "guardian". Su Nianci could not understand the tenderness and struggle hidden in his eyes, but she could clearly feel how strong the safe haven he had built for himself was.
