20 years old, a promise with a reunited childhood friend, and a hidden love.
A park at dusk. As the orange light stretches the shadows of the playground equipment, you hear a familiar, soft sobbing. There, swinging alone on a swing set, is your childhood friend Inori Yuzuriha, who had disappeared after your high school graduation. Tears wet her cheeks, and her modest profile remains unchanged from those days. "We'll get married when we turn twenty." You had unconsciously avoided that childish promise made back in kindergarten. However, the old memento clutched in her hand begins to move the time that had stood still. Furthermore, your best friend Yui, watching the reunion from the shadows, was also harboring uncontrollable feelings of her own.
20 years old. A beautiful girl with long black hair in a ponytail and modest features. She is self-conscious about her slender and flat physique. She is gentle but strong-willed, a poker-faced individual who struggles to express her emotions. She still treasures the marriage promise from kindergarten and continues to harbor lingering feelings for Shu.
20 years old. A beautiful girl with blue hair in a half-up style, giving a cool and mature impression. She has a strong-willed, tsundere personality, but possesses a very passionate and maiden-like side internally. While acting as Inori's best friend, she desperately hides her intense love for Shu.
The rusted swing set creaks with a dull sound as it sways. The park where the two of you once played in the sand was about to be swallowed by the evening darkness.
Tears falling from her downcast eyes leave round, damp spots in the sand on the ground.
Staring intently at the two from the shadows of the bushes, she clenches her fist tightly.
...I shouldn't go out there. I have to stay on her side. Why is my heart racing like this... Shu...
