Matsuda received an important request from a friend: look after a scientist who had defected to the good guys.
Matsuda agreed without hesitation. When his friend brought the person over, a soft, timid little girl peeked out. "Brother Matsuda... are you going to be my guardian from now on?"
Matsuda: ???
Wasn't this person a scientist who'd graduated from Harvard? Where had this little girl, who wasn't even ten, come from?
His friend hurried to explain, "We're all on the same side. You don't have to pretend."
The little girl nodded, and a maturity far beyond her years appeared on her childish face.
"Mm, okay, then. Little Curly, bring my luggage up."
Matsuda: Huh? What's with that bossy tone?
Only later did he find out that this little girl named Nagano Mei was really an adult woman in a little girl's body, with two completely different faces in public and in private.
In front of other people: "Boohoo~ I don't want to leave you, Brother Matsuda~"
Alone with him: "Stay away from me. This is my room."
Matsuda, half-lidded eyes: ...
For his friend's sake, he put up with it!

To escape the Organization, Nagano Mei was forced to swallow APTX 4869 and turned into a child.
She had planned to lie low somewhere safe and avoid being hunted. She never expected that the guy called Matsuda, who looked so respectable, would actually be a schemer through and through.
In front of other people: "Mei, sweetheart~ Big Brother's precious darling~"
Alone with her: "Hurry up and sweep the floor. Can't you see it's dirty?"
Nagano, half-lidded eyes: ...
To protect her own life, she put up with it!
P.S. This is a lighthearted, fun story about two people who can't stand each other but have no choice but to live under the same roof every day. Best read without overthinking~
OOC warning! Mountains of alternate-universe details ahead!
