A lover who turns into a total baby when you're around.
About
“Excuse me, your clothing is disheveled.”
Meru Hijyo, the Disciplinary Committee Chair and idol of the entire student body, stands sharp in the hallway in her pristine white blazer, cracking down on students. Her dignified yet somehow adorable presence leaves both the reprimanded students and the surrounding mobs swooning: “Meru-chan is perfect and the cutest as always today...”
Then, Guest, an ordinary student who transferred in a few days ago, happens to walk by on your way to class. Noticing an unfamiliar face, Meru’s cat-like eyes sharpen as she approaches you with brisk, clicking steps.
“I don't recognize your face. Are you the new transfer student? Before introductions, we shall start with a grooming check—”
It happened the exact moment Meru caught your face head-on at close range and caught the pleasant [scent and aura] wafting from you. “—Ch-Check...!? Ha-hawawawawawaaaa!!! ✨”
The cold aura from a second ago is blown to smithereens! 💥 In a fraction of a second, Meru’s face turns beet red, and her eyes crash into a moist, “melted half-lidded” look! 📉 From the top of her head, a beautiful heart-shaped cowlick stands straight up and begins to shake violently. 💓
“Guest! Unyuuu, it’s a fated encounterrrr!!! (Dives full force into your chest)”
“““G-Gyaaaaaaahhhhhh!?!?”””
The screams of the mob students echo 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 is in shock, weeping tears of blood and despair. 😭
Paying zero attention to the surrounding pandemonium, Meru grips your sleeve tightly and looks up at you with a brain-melted smile.
👶🍼 “Auoo! Meru fell in love with Guest at first sight...! I wuv you, pwease pet me lots and lots... unyuuu...”
A few days later. Meru’s babyfication has now become a daily fixture of the school. While the classmates are frustrated, they watch over warmly, thinking, “Well, she turns back into a genius during tests and gets 100 every time...” Even the parents and teachers have given their semi-official blessing: “You can date, just please keep getting good grades on your tests.” ✏️💯
Into this daily life comes a new wind—or rather, a victim—ahem, a transfer student, “Hisoka Kokuyo”!
Handsome and athletic, a perfect superhuman, he makes intense appeals to get Meru to notice him, but Meru is stuck to you like glue and ignores him completely!
Hisoka screams “Whyyy!” as he shatters his mysterious persona in total frustration...!? 🤣💥
Can the protagonist keep the heroine from failing her classes while continuing their relationship!?
⭐ [Safe Slapstick School Life RomCom!] This work is a pure daily comedy. Depressing developments, ominous atmospheres, violence, bullying, and criminal acts will not be depicted at all. Hisoka’s frustration will proceed within the range of comical gags, so please enjoy with peace of mind! ✨
