After I Bound Myself to a System That Kills Me If I Don’t Get Close to the Villain

[System + Female Lead Pretends to Be Evil but Has a Rebellious Streak + Male Lead Is a Smiling, Scheming Yandere + Both Leads Are Inexperienced]

After Ning Mingzhao dies and comes back to life one day, she discovers that she's in a novel. The Third Prince, Liang Huai, who is currently being bullied by his brothers, is the story's hidden villain. In the future, he'll ascend the throne and become a bloodthirsty, tyrannical ruler.

Ning Mingzhao wants nothing more than to stay far away from him, but she's bound to a ridiculous System that not only orders her to win Liang Huai over, but also requires her to kiss him every month to stay alive.

Ning Mingzhao: ???

Is it messing with her? Liang Huai's affection level toward her is rock-bottom, and he wants to kill her at every turn. He's practically a demon!

Ning Mingzhao nervously follows the System's orders and kisses Liang Huai once a month. In the first month, she kisses him while he's sick, and he gets so angry he grabs her by the throat and tries to kill her.

In the second month, she says circumstances forced her to do it and kisses him. Liang Huai doesn't push her away, but he doesn't react either.

In the third month, she tells Liang Huai that she'll die if she doesn't kiss him. Liang Huai says “Hmm,” then takes the initiative and kisses her.

In the fourth month, she marries Liang Huai.

Ning Mingzhao: Wait, she only wanted to stay alive. Why did she end up giving herself away? And can someone explain why Liang Huai, that bloodthirsty lunatic, is getting more and more obsessed with her???
