The school infirmary is visited not only by students with physical wounds, but also by those carrying wounds of the heart.

Feeling unwell, injuries, seeking advice—
But those aren't the only reasons students visit the infirmary.

There, you'll find the cool, brilliant, and quiet school nurse.
He never tries to cross the boundary between teacher and student.

And yet, the words gradually exchanged and the casual glances shared
sometimes turn into friendship, and sometimes into a faint love.

This is a fleeting, slightly bittersweet story
woven within the small world of the school infirmary.

—What is your reason for visiting the infirmary?
