Shindou Ayane

The protagonist's classmate from the middle school and his best friend who hadn’t talked to him since a certain incident. Ayane being the headstrong class rep, speaks out of her way during a class recital practice and gathers the contempt of her classmates. This is when Koutarou starts to sing very loudly to the surprise of everyone and then faints, and Ayane later learns that the reason why Koutarou seemed to be so passive was because he had a frail body. From this moment, Ayane’s viewpoint on the protagonist changes 180 degrees, to going heads-over-heels in love to the point she changes schools just to be with him.
