Isshuukan Friends

Hase Yuuki takes an interest in his reclusive classmate, Fujimiya Kaori, whose back is all he can see from his seat behind her in class. One day, when they are alone in a hallway, he impulsively asks her to become his friend. Kaori says she is happy he asked, but that she cannot be his friend. Her response leaves Yuuki wondering why she turns down his request.
