The Villain is Being Suspiciously Kind

She reincarnated as Citrina, the older sister of the heroine in a romantic fantasy novel.
Her role was to be killed by the villain while rolling around like a dog for her family.
So she decided to twist the original work by making friends with the villain and rehabilitating him.

“Rina, I’ll do everything you ask me to do.”

Good. After some failures, she got close to the villain.
He also seems to have become a perfectly virtuous person.
She thought she had saved her life, so she left to make some money.
She returned after succeeding.

“Don’t be too nice. …only to me.”
“I don’t act this way with other people.”

Desian, the novel’s villain, smiled kindly.

“I only act this way for you.”

Her sweet and affectionate friend is somewhat suspicious.

-From the text-

“I’ll ask you again. Use me.”
“…Me, use you?”
“That’s right.”
‘Use you?’
Citrina looked at him. Then the corners of his red lips curved upwards.
Looking at Citrina, Desian whispered repeatedly.
“Use me as you wish.”
With those words, Desian reached out to her. He slowly arranged the hair that had fallen in front of Citrina’s ear. It felt like his fingertips traced through Citrina’s hair little by little.
His cold hands chilled her.
“Instead…….”
Desian’s voice whispered in her ear.
“Don’t use anyone but me.”
