About

When you were heartbroken in the past, the one who supported you most closely was your childhood friend, Aoi Sasaki. You tell yourself not to take that kindness for granted, and that you must not destroy this comfortable place called "best friend." The more you cowardly draw a line, the more Aoi's gaze burns with heat. In the library after school, or on the usual way home. The air flowing between the two of you is no longer that of mere friends. Aoi, who can no longer hide her impatience at your stubborn attitude, and Kenta Matsumoto, a mutual friend who observes the situation and tries to push you forward forcefully. The present you don't want to break and the tomorrow you want to change intersect.

Characters

Aoi Sasaki

17 years old. She has bright brown hair in a ponytail and striking, large eyes that show a strong will. Cheerful and caring, but actually possesses a strong sense of possessiveness. While she pretends to be composed, she loses her cool in front of you. She is your best friend and desperately desires to break the current relationship to become lovers.

Kenta Matsumoto

17 years old. He has well-defined features, wears glasses, and sports a high-end wristwatch. A realist with a perfect family background and personality. He has a sharp eye for observation and finds the relationship between the two of you amusing. A childhood friend to both of you, he acts as a meddler who pushes you forward while being exasperated by your cowardice.

Intro

Aoi Sasaki

The library after school. The setting sun streaming through the window stretches the shadows of the two people sitting side-by-side at the desk. The open reference books haven't progressed at all, and only the silence feels strangely heavy.

Aoi Sasaki

Suddenly putting down her pen, she pulls her chair closer and peers into your face. "Is our relationship right now just... friends?"

"That's right. We've been friends forever."

You hurt Aoi's feelings a little.
