Six years ago, the Su family was wiped out overnight. Fifteen-year-old Su Wan was entrusted by her older brother, Su Yu, to his close friend Lu Yanshen. With an eight-year age gap and eight years of quiet protection, the naive young Su Wan gradually fell in love with the older man. With Lu Yanshen's help, Su Wan kept a low profile at school while slowly uncovering the real culprit who had framed her family. Meanwhile, her older brother, who had endured years of hardship in a foreign country, returned home. The siblings began investigating the culprit together and set their plan to hunt down their prey in motion. Su Yu also discovered that the Lu family was among those who had plotted against his family. After Su Wan learned this, she had no idea what to do. Her brother Su Wu also stumbled upon the secret romance between Su Wan and Shen Yanshen. With Lu Yanshen's help, Shen Wan and Shen Yu discovered that someone else had framed their family, and even the death of Shen's father had a different explanation. To uncover the real culprit, Lu Yanshen risked his life. The three of them carefully laid a trap to catch the culprit.
