The Ramparts of Ice Episode 4

Koyuki Hikawa doesn't like socializing, so she's built a high wall around her circle and is always alone in high school. But her peace is shattered when she meets Minato Amamiya—a boy who, for some unknown reason, repeatedly tries to intrude on her quiet world. This story doesn't just feature the two of them; there's the popular Miki, the incredibly carefree Minato, and the affable and kind-hearted member of the basketball team, Youta. This is the story of these four people, whose lives are a bit complicated, but their childhood and feelings for each other take them on a new journey. Will Koyuki be able to break the wall she has created?
