I'm Busy Protecting My Sister, While the CEO Keeps Clinging to Me

After being reborn, my only KPI is my big sister! In my previous life, my sister and my best friend ended up in a bad breakup. This time, Yu Xingmian becomes a fiercely protective little sister, determined to split up the doomed couple! Any man who gets close to my sister will explode on the spot! But then the best friend’s domineering CEO of a brother appears out of nowhere! He corners her against a wall, looking down at her with scorn. “Trying to use my little brother to get your foot in the Si family’s door? I’ve seen plenty of women like you!” Yu Xingmian smiles instead of getting angry, and teasingly traces a finger over his Adam’s apple. “Mr. Si, I’m not interested in green apples. I like men like you… ripe, mature older men.” Seeing his face turn dark, she strolls away. Yu Xingmian: “Stay away from my sister!” Si Yuchen: “Stay away from my wife!” Wait, who’s your wife?! And so, the whole school witnesses a curious sight: sister-obsessed Yu Xingmian follows her older sister every day, driving away her suitors (especially Si Yuze), while jealous Si Yuchen follows Yu Xingmian every day, driving away her suitors (especially his own younger brother)! Si Yuze: “Bro, are you sick or something?” Si Yuchen: “Get lost. Don’t get in the way of me pursuing my wife!” Yu Xingmian: “…Help! How do I get rid of this love-struck CEO?”
