Akiteru Ooboshi is a high schooler who lives by a strict code:
No pointless socializing, no girlfriend, and definitely no time-wasting youth—efficiency is everything.
So why is his best friend’s little sister, Iroha Kohinata, constantly hanging out at his house!?
His bed is taken over!
She pulls seductive stunts and stops just short on purpose!
An endless storm of annoying antics!!
At school, Iroha is known as a graceful honor student and adored by everyone—but for some reason, she’s only obnoxious around Akiteru.
Just as he's being overwhelmed by this hyper, clingy, and super cute "uzai-kawaii" girl, a cold and aloof girl named Mashiro enters the scene.
From that moment on, everything starts to change—
for Akiteru, Iroha, and the rest of their friends.
She’s clingy, pushy, and (even though I never asked for it) always around!
Get ready for a hilariously frustrating and irresistibly sweet high school rom-com!
Let the painfully awkward, adorably annoying love story begin!
