About
Synopsis Koyuki Hikawa is a high school student who struggles with social interaction and has built an "ice wall" around herself. This story follows her as she gradually opens her heart and grows through her interactions with her classmates: the friendly Minato Amamiya, Miki, who understands her well, and the somewhat clumsy Yota. Koyuki, Miki, Yota, and Minato form a close-knit group of four. Except for Koyuki, the other three have been friends since middle school because they attended the same cram school.
