After the unexpected death of her mother, nine-year-old Su Shuiji was taken back to the majestic Su family by her father whom she had never met. Here she met her half-brother Su Liran, who was six years older than her, and fell in love at first sight. Su Liran, who was originally very cold, gradually lost his defense against Shui Ji due to her pitiful, cute and timid character, and instead took great care of her. The tenderness of a series of trivial things in life, the frightening care again and again, and the helplessness of conspiracy and conspiracy made him unable to let go of her and made him fall in love with her, but she had no idea about it and only thought of her own wishful thinking. When she finally let go and left him, he understood his truest thoughts. A pair of grieving men and women who are entangled on the edge of ethics and love, let's see how they play out this ethical game of love between you and me. (In the end, she found out that he was not his biological brother - if you want to know the funeral, please stay tuned.)
