Dangerous Her

Ten years ago, the Shen siblings, along with Lu Manman and Cheng Yuan, relentlessly framed Song Chu, a student from a poor family, solely to prevent her exceptional talent from taking away their honors. Shen Yin instigated her brother, Shen Xiao, to approach Song Chu, causing her to fall in love. However, Shen Xiao genuinely loved Song Chu. Jealous, Shen Yin frequently spread rumors and slanders against Song Chu, ultimately leading to Lu Manman pushing Song Chu down the stairs. Shen Xiao, arriving at the scene and witnessing this, simply fled with his sister, Shen Yin. Everyone believed Song Chu was dead, unaware that she had miraculously survived and was secretly gathering strength for revenge. Ten years later, Shen Xiao's guilt towards Song Chu deepened. While celebrating Shen Yin's achievements at a bar, Shen Yin angrily left because her brother, Shen Xiao, was still wearing Song Chu's hair tie. At this moment, Song Chu, dressed in her finest attire, appeared before Shen Xiao and had sex with him. Shen Xiao… Upon waking, Song Chu found herself gone, but unexpectedly encountered Cheng Yuan, one of the perpetrators of her past abuse. When everyone thought they had mistaken her for someone else, Song Chu appeared at Shen Yin's lecture as a cleaner, yet still faced suppression from the villains. To further her revenge plan, Song Chu orchestrated contact with Song Yuanshan, the head of the Song family, and used his incriminating evidence to blackmail him into a contract, ultimately making her the stepmother of the Shen siblings. As Song Chu's revenge unfolded, the truth of what happened back then gradually surfaced. The harm Song Chu suffered went far beyond this; she gradually exposed the group of young masters and ladies who abused their power, the snobbish teacher who acted indiscriminately, and the murderer who killed her mother! Song Chu was determined to seek justice for herself and her mother, uncover all the conspiracies, and avenge her ten years of silence and endless suffering.
