Isshuukan Friends.

Definition

Sixteen-year-old Yuuki Hase finally finds the courage to speak to his crush and ask her if she wants to become friends. The object of his affection, Kaori Fujimiya, is a quiet and reserved girl who cuts herself off from everyone and does not spare him the same blunt rejection she gives everybody else.
