Kinusa Shiori

The heroine of the third story, the protagonist's childhood friend. For a long time, she has been harboring her feelings for the protagonist.

Shiori originally had a weak body, which resulted in her being a bit withdrawn. Therefore, taking a step forward from being a "childhood friend," was a difficult task for her. And for Shiori, she is fine with it as long as the four of them stay friends, and it cannot be anything else, however......

Before she knows it, her group of friends has become completely different than before. When she learns of it, the feelings she had kept inside finally blossoms, like the blooming of a large sunflower.
