The Male Lead of My Thesis Went on a Rampage

Shen Yuewei accidentally transmigrates into the world of her thesis, where the male lead, Xiao Heng, lives. Completely bewildered, she knows only that Xiao Heng will eventually become the chief minister, second only to The Outcast and above everyone else. He kills without mercy and is utterly ruthless. Even more tragically, she is merely an insignificant supporting character. The original owner was timid and cowardly, raised in her uncle's household, and used by the Second Prince, leading to her entire family being killed! Good heavens, what a disastrous start from the start! The early part is a little confusing, the middle is a little angsty, the later part is a little sweet, and the ending is a little sad~
