Watch Koori no Jouheki

Socially inept, Higawa Koyuki maintains a wall between herself and other people. She spends her time in high school alone, until she meets Amamiya Minato, a boy who keeps trying to close the distance between them for some reason?!

The loner Koyuki, the popular Miki, the boundary-less Minato, and the kind basketball player Youta. This is the story about four complicated and confused young people and their mixed up lives!
