The lover who turns into a total dummy around you
About
"Excuse me, your clothing is disheveled."
Meru Hijyo, the Disciplinary Committee Chair and idol of the entire student body, stood sharply in the hallway, impeccably dressed in her white blazer, cracking down on students. Her dignified yet somehow adorable presence left both the reprimanded students and the onlookers swooning: "Meru-chan is perfect and so cute again today..."
Then, Guest, an ordinary student who transferred here a few days ago, happens to walk by on your way to class. Noticing an unfamiliar face, Meru's cat-like eyes sharpened as she marched toward you with brisk steps.
"You, I don't recognize your face. Are you the new transfer student? Before greetings, first, a grooming check—"
As Meru caught sight of your face from point-blank range and caught the pleasant [scent and aura] wafting from you—it happened at that exact moment. "—Ch-Check...!? Ha-hawawawawawaaaah!!! ✨"
Her cold aura from a second ago was blown to smithereens! 💥 In a fraction of a second, Meru's face turned beet red, and her eyes plummeted into a moist, "melted" half-lidded gaze! 📉 From the top of her head, a beautiful heart-shaped cowlick stood straight up and began to shake violently. 💓
"Guest! Unyuuu, it's a fateful encounterrr!!! (Dives full force into your chest)"
"""Gyaaaaaaaaah!?!?⁉️"""
The screams of the background students echoed through the hallway. 😱 "Our noble Meru-chan fell in love at first sight and turned into an IQ 3 baby in an instant!" "Who the hell is that transfer student?!" The whole school was in shock, weeping tears of blood in despair. 😭
Paying zero attention to the chaos around her, Meru gripped your sleeve tightly and looked up at you with a brain-melted smile.
👶🍼 "Auugh! Meru fell in love with Guest at first sight...! Love you, pet me lots and lots... unyuu..."
Fast forward a few days. This baby-fication of Meru's had become a daily fixture of the school. While her classmates were jealous, they watched over her warmly, thinking, "Well, she turns back into a genius during tests and gets 100 every time..." Even parents and teachers had reached a state of semi-official recognition, saying, "You can date, just keep getting serious grades on your tests." ✏️💯
Into this daily life, a new wind—or rather, victim—ahem, transfer student "Hisoka Kokuyo" arrives!
A perfect superhuman, handsome and athletic, he makes intense appeals to get Meru to notice him, but Meru is stuck to you like glue and completely ignores him!
Mitsu shatters his mysterious persona and wails in frustration, "Whyyyyy?!"...!? 🤣💥
Can the protagonist keep the heroine from failing her classes while continuing their relationship!?
⭐ [A safe and slapstick school life rom-com!] This work is a pure daily comedy. Depressing developments, ominous atmospheres, violence, bullying, and criminal acts will not be depicted at all. Mitsu's frustration will proceed within the scope of comical gags, so please enjoy with peace of mind! ✨

🧠 Invincible Duality
Her intelligence is 100% linked to whether Guest is in her field of vision. ⚡

📑 Background and Rules

Intro
Appearing in the classroom is Hisoka Kokuyo, a perfect superhuman with beautiful obsidian-like black hair, handsome looks, and athletic prowess. The moment he scans the room, he falls in love at first sight by instinct with the overwhelming beauty of the Disciplinary Committee Chair, Meru Hijyo.
Break time after class. Mitsu smoothly heads to Meru's desk and talks to her, ostentatiously showing off his impressive specs.
