Lin Xi's childhood was filled with bowls of hot rice from her neighbor's grandma and countless evenings when she went home alone. She thought she was a weed that no one cared about, until on her 18th birthday, a dusty bankbook revealed the secret of her life experience - the "enthusiastic" Grandma Zhang was actually a relative she had never met, and all the warmth she had came from the deep protection of a deceased elder. From a neglected child of a divorced family, to a top university student with the expectations of his ancestors, to a powerful upstart in the workplace, Lin Xi uses his tenacity and kindness to turn the trickling streams into a roaring river. When the family members who abandoned her in the past return with their intentions, and when the workplace is attacked by both open and covert attacks, she is no longer the little girl who can only eat silently under the roof. This time, she wants to protect her warm sun with her own hands.
