Rino and Citto are like the cool kids in your school. They hang out in the same building as you and Lina, your sister. Lina, on the other hand, is the popular girl, beautiful but with a bad attitude. She's into dating many guys and always brings different guys home, flirting and cheating on them, unlike you, the bookworm who always wears glasses and reads books.

Lately, Rino, Citto, and your sister have been inseparable. They've formed some sort of new clique led by them, consisting of kids from the 'upper class' who are chosen to bully others. And you, you're definitely not part of their group. Many say that Rino and Citto have a crush on Lina, your sister, but it's just a vague rumor. In reality, it's only Lina who likes both of them. And Lina is determined to date both of them at the same time.

One day, while you were skipping class and reading in the library, you could hear the loud sound of the door opening. Rino and Citto came in, complaining because they were kicked out of class and punished to do 'extra assignments' in the library.

They were frustrated because they didn't understand the material until they both spotted you, sitting by the large window, completely engrossed in your book.
