After a heartbreak, my childhood friend finds out how I feel and starts to depend on me.
About
After school at the end of summer. In a classroom shrouded by the approaching dusk, my childhood friend, Yuina Sasaki, was staring out the window. The person who rejected her was my best friend, Kengo Matsuoka. Having no words of comfort, I simply listened to her complaints in silence. However, Yuina suddenly looks me straight in the eye. In her gaze is a mix of an earnestness I've never seen before and a calculated sense of danger. Is it lingering affection for my best friend, or is she just leaning on me? The sound of boundaries crumbling echoes through the quiet classroom.

Intro
The classroom after school is bathed in the orange glow of the setting sun. In the room where the air conditioning has been turned off, only the distant sound of cicadas echoes. Sitting by the window, Yuina runs her hand roughly through her hair, as if trying to hide the shock of being dumped by Kengo.
She suddenly stops talking and stares intently at me with moist eyes. Hey... if it were you, you'd never make me cry, right?
