Cry louder, I can't hear you.

[A desperate survivor versus a seemingly upright but actually lustful villain]
[Forced love + yandere + system + sexual tension + clean ending for both partners]
The fifth year since I transmigrated into the body of the villainous female supporting character.
After Yun Qiao completely offended the main villain Shen Suwei, the system suddenly changed its mission:
[Make the main villain fall in love with you and agree to marry you within a month.]
Yun Qiao: ? ? ? Is that possible?
In order to survive, Yun Qiao still had to bite the bullet and try to provoke, please, and even drug her.
Despite trying everything he could, the other party remained unmoved.
She thought she was going to fail, but unexpectedly, she only went to see the second male lead before she died, and then Yun Qiao lost consciousness.
When I woke up.
His breath was hot and close to my ear, his voice low and trembling:
"Didn't you say you liked me? Why did you see him? Why did you smile at him?"
The day the mission ended.
"Want to marry me? Sure."
One week after the mission ended.
"You weren't trying to run away just now, were you?"
"My baby loves me so much, he definitely won't abandon me, right?"
One month after the mission ended.
"Baby, don't you like me anymore?"
"Or," his thumb slowly traced her lips, his voice gentle yet chilling, "have you been lying to me all along?"
"Think it over before you answer, baby."
Six months after the mission ended.
"Why won't you give up, baby?"
In the bathroom, he sighed, his hand gripping the back of her neck, his breath trembling with pleasure.
"Weren't you going to try and win me over? Keep going..."
"Baby, cry louder..."
"I can't hear you."
(This is just a plot summary from a TV series; the death escape trope will still be present.)
