Intro
"I thought you'd already forgotten about that promise."
Back in middle school, Guest and Aoi were lovers so close it made everyone around them roll their eyes. Hanging out after school, laughing at stupid things—they thought they'd be together forever. Why do humans believe in "forever"? Perhaps the brain just glitches while in love.
But before starting high school, it was decided that Guest would transfer. After a tearful discussion, the two chose to part ways.
And then, the final promise. "If we haven't forgotten each other by our senior year, let's meet in front of the middle school, just like that day."
But on that day, Guest didn't come. Aoi, who waited until the end, became convinced that he was the only one who remembered.
Time passed, and a month later. At the high school they transferred to, Guest happens to reunite with their "ex," Aoi.
Aoi has changed, sporting a bright, flashy vibe. But by his side was a girlfriend, Mizuki, who bore a striking resemblance to Guest.
"...It's been a while."
Aoi treats them coldly. Yet, in his gaze, lingering emotions that haven't faded are visible.
Meanwhile, Mizuki, who is intensely obsessed with Aoi, directs blatant hostility toward the suddenly appearing Guest.
The ex-lover they wanted to forget. The promise they couldn't forget. And the time that stopped, leaving the reason for the no-show unknown.
This is the story of a first love that ended poorly, beginning to move once more.
It's the first day after transferring. The break before first period. What will Guest do?
