She likes the librarian in the school library.
In order to see him, she ran to the library every day, in fact buried in a pile of books, her eyes kept peeping at him sitting at the table near the door. I borrowed a few books every day just to see him smile at himself.
After seeing her junior from her freshman year, she finally offered courage to confess.
But she didn't find out that every librarian only did it once, and only he did it for three consecutive years.
