【Bullet Comments (Danmu) × Sweet Romance × Awakening × Modern × Yandere × Gloomy/Clingy × Heiress × Professor】

A story about a cunning, yandere sweetheart with overwhelming possessiveness who fights for, steals, and ultimately wins the heart of her unattainable white moonlight heiress.

One day, Cheng Jianwei suddenly begins seeing mysterious strings of floating text before her eyes. The comments reveal a shocking truth: she's nothing more than the vicious supporting villain in a melodramatic redemption novel.

She—brilliant beyond compare, emotionally intelligent, wealthy, beautiful, practically the perfect human being—is only a supporting character?

Then just what kind of person is the heroine supposed to be?

The answer arrives the day a pure, obedient, kind, and adorable young woman with sparkling eyes appears before her.

In that instant, Cheng Jianwei makes up her mind.

Who says only the male lead can save the heroine?

As the villainess, she'll do it herself!

【Let go of our precious little sister! You evil old hag!】

"Heh. Nope."

Late one quiet night, Cheng Jianwei gazes at Lu Xingyao's sleeping face.

Why does something about this feel... off?

Only then does she realize that from the very beginning, she had already stepped into a vast web carefully woven just for her.

"Big Sis, you're mine... and you can only be mine!"
