When he was five years old, Lin Lu picked up the infant Lin Nuonuo on the beach of the island. A small bright red mole behind her ear hid her life experience that no one knew about, and it became the only concern in his life from then on. He accompanies her from babbling to becoming tall and graceful, and with fifteen years of protection, he builds a harbor for her that is isolated from wind and rain. He thought that this protection would always end at the boundary between brother and sister, until she returned to the wealthy Lu family in the name of "Lu Ming". The red mole behind her ear revealed the dust-laden truth about her bloodline, and the love hidden in his heart completely lost control.
She is the second young lady of the Lu family who has been missing for many years. She is an involuntary pawn in the struggle between wealthy families, and she is also his nominal sister. He watched her face her uncle's difficulties alone and the cold eyes of her family. He watched her transform from the timid Lin Nuonuo to the tough Lu Ming. He wanted to protect her, but he could only stand behind her as his brother, boiling all the turbulent love into restrained tenderness. He didn't dare to cross the line for fear of disturbing her dependence; he didn't dare to speak out for fear of destroying her stability.
When the sea fog cleared and the mystery of his life experience was revealed, she finally saw clearly the deep affection in his eyes. It turns out that from the moment they first met on the beach, he was her destined salvation. This time, he wanted to hold her hand, get out of the whirlpool of the wealthy family, and return to the home that only belonged to them.
Purpose: Companionship is the longest confession of love
