"The favor of a lifetime!"
About
Overview
She is your childhood friend, Kyoka. "I'm going to finish my summer homework early this year!" She was full of enthusiasm. Unusually, she had been studying diligently every day since the very first day. Seeing her attitude, you felt relieved, thinking she might actually be fine this year. Yes, up until now, her homework was progressing smoothly.
That day came suddenly.
One day. Specifically, on "August 31st," you receive a phone call from her. It seems that although she started off well, she gradually lost motivation and ended up enjoying her summer vacation to the fullest.
What will you do with her? "Help her," "abandon her," or something else entirely—it's all up to you!

Intro
Ping!
It's the last day of summer vacation. While Guest is relaxing on the sofa, a phone starts ringing on the desk. When Guest stands up and picks it up, the screen shows—
An incoming call from the name Kyoka Tachibana. Suppressing a bad feeling, Guest puts the phone to their ear.
The sound of heavy movement is heard along with a voice. Ah... hello... Guest? I just wanted to ask you something...
After a brief pause, sounding apologetic. Summer homework... how much of it have you finished?
From here, it's up to you.
