[Adorable, sweet college girl x Gloomy, suspicious, self-deluding yandere beauty]
An accident awakens Shi Yijin's self-awareness.
Only then does she learn that she's actually a substitute bride in a wealthy-family novel, taking her older sister's place to bring good luck to the family, and destined for a miserable ending.
The System bound to her tells her that if she doesn't want to be a disposable character, she needs to soak up more of the protagonist's luck. Ways to do so include, but aren't limited to, holding hands and hugging...
Shi Yijin's eyes light up. There's a way to do that? Then who is the protagonist...?
The System: The person you're marrying to bring good luck this time, Pei Zhaoxi.
Looking at the sickly woman lying unconscious in bed, who supposedly can only use a wheelchair for the rest of her life after that accident, Shi Yijin immediately tears up. She carefully lifts the woman's fingertips and presses them to her cheek.
My savior!
This is my future savior!

But the System's information is incomplete. It doesn't know that Pei Zhaoxi is pretending to be ill.
Pei Zhaoxi waits coldly for the little wife forced to marry her as a substitute to show her true colors.
Instead, the other woman only lifts her fingertips and presses them to her cheek, treating her as if she were precious and handling her with the utmost care. Afterward, she smiles with an especially sweet look in her eyes.
Pei Zhaoxi: ...?
The more she watches, the more shocked she becomes.
Her little wife has no resentment at all. When people look down on Pei Zhaoxi for being disabled, she angrily stands up for her. She pushes her outside to enjoy the sun, tirelessly gives her massages with her own hands every day, and says she's the best person in the world.
She takes care of her meticulously, and even a hug is enough to make her little face turn bright red with happiness.
Pei Zhaoxi: lost in thought.
Could she actually... be completely in love with me?
No one expected that Pei Zhaoxi would ever "recover."
With ruthless methods, she seizes power, deals with the scheming people who kicked her when she was down, and knocks all the other heirs out of the running.
On the very day she becomes head of the Pei family, just as the original novel's ending describes, the System on Shi Yijin is exposed as well. Pei Zhaoxi discovers that Shi Yijin has been soaking up her luck all along.
Seeing Pei Zhaoxi's dark expression, Shi Yijin decides to run away in the middle of the night.
Unfortunately, she doesn't get far before she's caught and dragged back.
"Where do you think you're going, my dear Yijin?" Pei Zhaoxi grips the back of her neck. Her pupils are filled with intense, repressed possessiveness as she asks dangerously, "Whose luck do you want to soak up besides mine?"

Later, in the middle of the night.
Shi Yijin covers her swollen lips, dizzy and disoriented as she whispers a plea: "Sis, dear Sis, no more kissing. I've gotten enough luck already..."
"Have you really gotten enough?"
With tearful eyes, she nods, but Pei Zhaoxi says meaningfully, "I don't think it's quite enough. Why don't we do something that makes it easier for you to soak up my luck?"
