[Mind reading + adored by the whole family + precious little sister + sweet romance + unbelievably adorable contrast + everyone's character goes off the rails]
Bad news: Su Youyou, a miserable corporate drone, chokes to death on a mouthful of luosifen.
Good news: She transmigrates.
But she transmigrates into the role of a vicious biological heiress with a miserable ending, starting right when she's reclaimed by her wealthy family.
The sheltered biological heiress is blinded by jealousy. She starts making life difficult for the fake heiress, the female lead, and tries every trick to get attention from her parents and four rich older brothers. Instead, she makes a fool of herself, and her wicked schemes fail again and again. In the end, her whole family rejects her and throws her out. She is kidnapped, held for ransom, and dies a miserable death.
Corporate drone Su Youyou thinks the original female lead is far too narrow-minded. Very narrow-minded indeed.
They're both rich heiresses now, so why fight? Wouldn't it be better to lie flat and be a happy little fish?
But what Su Youyou doesn't expect is that the golden finger she gets along with her transmigration opens the door to a whole new world.
She can hear what her family is thinking. The problem is, everyone is two-faced.
The stern, old-fashioned CEO father is actually a hopeless romantic?
The calm and reserved eldest brother and heir, huh? A plushie fanatic? What did you say you're hiding in your secret room?
The arrogant, cool, and dazzling actor second brother, huh? Sensitive and fragile?
And wait, the sunny, handsome third brother always hides under his blanket to cry? The taciturn, aloof top student fourth brother can't even take care of himself?
Even the cool, sophisticated fake-heiress female lead turns out to be a secret little-sister fanatic?
It's broken, it's all broken, it's the end of the world!
Su Youyou says, Go ahead and fall apart, just don't kick me out.
