Shen Yinian is the fake heiress of a wealthy family, switched at birth.
The day the true heiress, Shen Muhuan, returns, Yinian gets bound to the [Cheesy Pickup Lines Survival System].
If she doesn’t say pickup lines, she’ll die.
And so
To her icy adoptive brother: “Hey, where are you from? You’re the one my heart belongs to.”
To her stern adoptive father: “Dad, are you an architect? You built a room in my heart.”
To her gentle adoptive mother: “Mom, there’s something on your face… you’re so pretty.”
The whole family: ??? Has she finally lost it?
Later
Her adoptive father, eyes red, sends her money. “Say more, Dad loves hearing it!”
Her adoptive mother covers her face, giggling. “Yinian is finally willing to act cute!”
Her icy older brother secretly starts studying pickup lines. “Need help? I can learn.”
Her true-heiress sister gently takes her side. “Whatever my sister says is right!”
Even Jiang Lebai, the aloof heartthrob admired by the whole school, goes from “Classmate, come up with something more original” to showing up on time every morning, noon, and night:
“Shen Yinian, do you know the difference between you and the moon? The moon is in the sky, but you’re in my heart.”
“Shen Yinian, do I have a cold? I seem to have no resistance to you.”
“Shen Yinian, I’ve booked you for your next life. Save me a spot.”
Shen Yinian: Wait, the System never said it would turn the male lead into a pickup-line machine too!
