Maybe: Jirai Onna

Despite the school's uniform policy, Nonoka Himekawa's eccentric way of dressing puts her at odds with the rest of her classmates and lands her the label of "landmine princess." The sole person she can confide in is her only friend, Mizuki Endo, who tries her best to help Nonoka change her image and become more approachable. But what seems like a private interaction between two friends catches the attention of a passerby, changing Nonoka's woes almost overnight.
