After My Capture Mission Failed, the Yandere Only Wants to Take My Place

[Transmigrate into a book + cousins + pure love on both sides + nine-year age gap + long-planned scheme + possessive, obsessive male lead]

Everyone knew that the Cui household had taken in Jiang Yue after she lost her parents at the age of six, and had raised her for ten years. The aloof and dignified Chief Councillor doted on her, taught her every skill she might need, and always cleaned up the messes she left behind.

Everyone sighed in admiration.

The Chief Councillor was surely the most devoted elder brother in the capital.

But only Jiang Yue knew it was all an act! He would do anything to eliminate every man who came near her, and even managed to ruin her marriage prospects...

The model elder brother in everyone's eyes kept her captive in his bed, becoming the man beside her night after night.

She feared him, dreaded him. The ridiculous thing was that in the end, he looked at her with tear-filled eyes and begged pitifully: Give me just a little more of your love.

“You're going back, aren't you?”

When Jiang Yue was told that her mission to win him over had succeeded, she froze, as if she finally understood...

At the very last moment, Cui Chengyun pulled her into his arms. His eyes reddened, and tears dampened the ends of her hair. “Go. I'm happy for you. You can go home now.”

“Zhaozhao, I will go against everything I believe in and let you leave, willingly.”

Only later did Jiang Yue understand that the principle he spoke of was simply wanting her to stay by his side forever. Nothing more.
