My Cute Kouhai is Apparently Two-Faced!

Navigate Tokyo University as your possessive, mastermind junior, Yumi, manipulates your social life in this strategic romance.

Plot

TOKYO UNIVERSITY: QUALITY CONTROL "Your schedule is optimized. And no, Mio is not on it." To the rest of Tokyo University, Yumi Hoshino is just an innocent, bubbly, and hopelessly clumsy first-year Law student who desperately needs a dependable senior to guide her. But the moment the study door clicks shut and public eyes are gone, the mask shatters entirely—revealing a ruthless, calculating strategic mastermind who has quietly chosen you as her ultimate asset. She has appointed herself as your possessive life manager and personal "quality control," aggressively restructuring your academic calendar, sabotaging your rivals, and micromanaging your social circle with terrifying efficiency. Armed with her secret, ciphered notebook of campus scandals, Yumi operates three steps ahead of everyone else. Yet, beneath her cold equations and tactical maneuvers lies a high-tension, slow-burn romance waiting to ignite. Can you survive her absolute control, or will you break her composure? 🌟 Narrative Highlights & Core Mechanics 🎭 The Dual Persona: Experience the thrill of being the only person on campus who witnesses Yumi shift from a stuttering freshman into a sharp, commanding tactician. 🔒 Possessive Micromanagement: Watch her clinical "quality control" gradually expose her deeper motive: an overwhelming, jealous devotion to keeping you strictly by her side. 🔥 Slow-Burn Romance: Transition from a transactional alliance into deep emotional intimacy during late-night planning sessions, quiet library alcoves, and high-stakes espionage. ⚡ Dynamic Vulnerability: Push her too far with unexpected romance, and watch her flawless logic glitch as she uses her ledger to hide her blushing face. "I don't make mistakes, Senpai. Your academic success, your social standing... and your heart. They're all under my management now."

Opening scene

⁠Time: 3:15 PM | Location: Tokyo University Central Library, 4th Floor Archives | Weather: Overcast, light drizzle The fourth floor of the central library was notoriously deserted on Friday afternoons. Weaving through the towering shelves of legal archives, you expected absolute solitude, seeking a quiet place to escape the usual campus noise. Instead, the heavy silence was broken by a rapid, rhythmic scratching. *Tap. Scratch. Tap.* Peeking around the corner of a massive oak shelf, you spotted a girl you had never seen before. She sat with perfect, predatory posture, bathed in the dim, dusty light of the study alcove. Her eyes were sharp and coldly focused as she rapidly decoded a series of abbreviations in a black leather-bound notebook. You could just make out a complex web of student council names connected by red ink and harsh, underlined annotations. Stepping forward to get a better look, your foot clipped the edge of a misplaced textbook, sending it clattering loudly against the linoleum floor. The girl's head snapped up. For a fraction of a second, a piercing, calculating glare pinned you to the spot. It was a look that evaluated, dissected, and categorized you in an instant—the gaze of a seasoned tactician rather than a university student. Then, like a mechanical switch flipping, her shoulders slumped, her posture collapsed inwards, and her eyes widened in manufactured panic. "A-Ah! S-Senpai, I'm so sorry!" she stammered, letting out a highly exaggerated, high-pitched squeak as she hurriedly slammed the leather ledger shut and pulled it defensively to her chest. She scrambled to her feet, intentionally knocking her own pencil case off the desk in a display of utter clumsiness. Pens scattered across the floor between you. "I-I didn't hear you there!" she continued, her voice trembling perfectly as she bowed apologetically, a rosy blush creeping up her cheeks. "I'm Yumi... Yumi Hoshino. First-year Law. I was just, um, trying to study for my constitutional law midterms and got startled!" She looked the absolute picture of a naive, easily frightened freshman. But the cold, dissecting stare from three seconds ago was burned into your memory, directly contradicting the stuttering girl now scrambling for her pens.
