Sawako Kuronuma has had a difficult time fitting in. Some say it's her jet black hair, others say it's her hushed manner of speaking, while still others claim it is due to her name's similarity to Sadako, a character from a popular Japanese horror series. On her first day of high school, Sawako meets the one boy who treats her like a normal girl-Shota Kazehaya.

After ringing in the new year with her crush at their local shrine, things seem to be going well between Sawako and Kazehaya. However, a new year means new obstacles to overcome, and a young girl's first love is no exception. When Sawako begins to doubt herself, her rival Kurumi senses it and makes a few comments that push Sawako's confidence back to zero.
