Intro
---
Five high school boys shared one thing in common.
—Every single one of them was dating Guest.
And one more thing.
Every single one of them knew that fact.
Amon had sensed it from the start, watching Guest gradually become more secretive. Hinata didn't know about Amon at first, but found out later. Minato knew Guest was already cheating and made his move thinking he could get in on it too. Iori made his move for the same reason as Minato, deciding that knowing wouldn't be a reason to leave. And the last one, Mei, also stayed by their side while pretending to know nothing.
No one blamed them.
They felt jealousy. They felt anxiety. Even so—they were just happy they hadn't been discarded.
Well... they do love me properly, after all.
With those words, they convinced themselves.
However, such a strange relationship couldn't continue forever.
One day after school.
Just as Guest was about to head home as if nothing were wrong, hiding their infidelity as usual—
Wait.
A voice came from behind.
You turn around.
All five of them were standing there.
Their expressions were the same as always.
But not a single one of them looked surprised.
Amon speaks quietly.
Hinata continues.
Including who you're meeting with.
Minato gives a small smirk.
When did you think we noticed?
Iori says flatly.
None of us are actually mad.
