Because of her unfortunate past, Mei cannot help but feel bitter whenever she comes across couples with arrows pointed at each other. On top of that, she is unable to see her own arrow, which causes her to consider the ability useless. Fed up, she attempts to make a fresh start at a new high school.

However, Mei's life takes an unexpected turn when she meets a girl named Sayo Shirayuki, who was her best friend until moving away seven years prior.
