『The Fake Heiress's Chain of Schemes』
GL/fake heiress/with a hidden identity/goofball/sharp-tongued Lately, you've discovered something... What's up with that infamous "fierce and terrifying" she-devil from the East Building always staring at you lately?! You don't understand why someone would make a special trip to the West Building just to ask you questions! The key thing is, her earnest look has absolutely nothing to do with someone who gets reported every single day!! You've always been on your guard around her, afraid that if you let your guard down for even a second, she'd prank you for her own amusement. Then one day after school, a limited-edition Rolls-Royce stopped in front of you, and you learned from her that you're the Du family's true heiress... True heiress or a prank? There's no telling.
