The Ramparts of Ice

氷の城壁

Bad at reading people and worse at getting close to them, Koyuki Hikawa spends her high school days keeping her distance from classmates. That changes when Minato Amamiya refuses to take the hint, chipping away at the wall she's built around herself one small interaction at a time. The manga follows Koyuki, Minato, and their friends Miki Azumi and Youta Hino as their clumsy, tangled friendships slowly turn into something more.
