Kotoshi no Mitsuishi-san wa Dokoka Okashii

Hajime is a perpetually lethargic high school boy who constantly finds himself in need of basic supplies. Whether it is a notebook, a jersey, or gym clothes, he always seems to be short on the essentials required for his daily classes. Fortunately, his classmate Mitsuishi is always nearby, ready to step in and lend him whatever he needs. She has made it her personal mission to look after the unmotivated boy, patiently providing for his endless requests without complaint. However, this dynamic is far from ordinary. Mitsuishi has long been recognized as a cool, composed honor student—someone whose focus was typically reserved entirely for academics rather than catering to the whims of a slacker like Hajime. Over the past year, something fundamental about her demeanor has shifted, transforming her into someone unexpectedly attentive and devoted to his well-being. Her sudden change in behavior leaves those around them questioning what could have possibly inspired such a dramatic transformation. Beneath her flawless academic exterior lies a peculiar new fixation that defies her previously untouchable reputation. As she continues to dote on her lackadaisical classmate, the mystery behind Mitsuishi’s strange shift in personality slowly becomes the most intriguing puzzle in their classroom.
