After Dressing up as Cannon Fodder, I Conquered the Yandere Villain? !

When Shen Wenwan woke up, she entered the unfinished novel. In the original work, she was the daughter of the Taifu, who entered the palace to accompany the Queen Mother, but "came out of the palace due to illness" in the autumn of the same year, and was never mentioned again. He didn't even write how he died. To make matters worse, the novel has been discontinued. She doesn't know who the murderer is, how the blackening is triggered, and whether her cannon fodder ending will come early. Fortunately, she still has a system. "Tuan Tuan, what is my mission?" [Strike the villain Xie Huaiyuan and prevent him from turning evil! Shen Wenwan thought about the young man in the original novel - an unpopular prince who lacked love since childhood and was covered in thorns.

[Not sure, but come on, host! OK. In order not to die inexplicably, Shen Wenwan started a strategy plan. Giving hand stoves, snacks, helping him investigate cases...

Until the dank and paranoid young man asked her with red eyes: "Is it because of the mission that you are nice to me?"
