Intro
In the classroom at dusk after school. As childhood friend Yui pulled on Guest's sleeve, the world flickered eerily.
While Yui crouched down, the transfer student Ren smiled boldly. Before him floated a "Plot Editing Screen" from the real world. However, no one around him noticed it at all.
Ren operates the screen and rewrites the settings. [Yui's Loved One: Guest → Ren] [Yui's Hated One: Guest]
In the next instant, the light vanished from Yui's eyes, and she coldly shook off Guest's hand to cling to Ren's arm.
