After Dressing up as a Cannon Fodder Senior Sister, I Was Spoiled by Mind Readers.

The unlucky Su Qinqin transformed into the evil senior sister that everyone disliked in a Mary Su fairy novel. The original owner was unruly and domineering, acted viciously, framed the heroine many times without success, and was eventually killed by her junior brother with a sword through the heart. In order to survive, Su Qinqin frantically improved her favorability among many male supporting actors, but little did she know that everything she did was seen by her junior brother. The second junior brother is young and promising, gentle as water, but suffers from a secret love for the heroine and is trapped by love poison all day long. Su Qinqin immediately picked up the antidote for her second junior brother: Second Junior Brother, brave people enjoy the world first. You can fly bravely, but I will always be with you, senior sister! The third junior brother is arrogant and domineering, but the dignified little prince has suddenly become the abandoned son of the previous dynasty. He is smiling on the outside, but secretly he wants to destroy the whole world. The only beauty he loves but dares not touch is the heroine, who has given birth to inner demons amidst all kinds of pain. Su Qinqin directly locked the two of them in a room: Third Junior Brother, leave the matter to me, don't worry! The iceberg beauty master encountered a bottleneck in his cultivation. He thought about how to eliminate his love disaster every day, and almost went crazy. Su Qinqin presented her demon pill: Master, if you eat this pill, you will be able to break through! She never knew that her junior brother, who was so perceptive to everything, could actually hear all her thoughts! The yandere little junior brother: Senior sister, instead of trying to please them, why not please me? I don't want anything but you. Su Qinqin: I won't be able to fix it all at once.
