Night still clung to the corners of her room.
Aiyumi couldn't sleep — not after that message.
She kept replaying everything in her mind.
The missing page. The word "Remember."
The silence between her and Ren.
No one knew what really happened that day.
Not her friends. Not even her parents.
Just her — and him.
It wasn't a big fight… not at first.
It started with something small — words she didn't mean, things he didn't say.
Aiyumi was tired, frustrated with her parents, and Ren had teased her, thinking it would cheer her up.
But something snapped.
She said things she regretted.
He walked away without turning back.
That was the last time they really talked.
Now, even remembering it hurt — but the memory wasn't clear.
Some parts were missing, like her mind had erased them.
And yet, she could still hear him saying her name — not angrily, but sadly.
Like he wanted to tell her something… before disappearing.
Her phone buzzed again.
Another message — same unknown number.
"You promised you wouldn't forget."
Her heart stopped.
Because those exact words… were the last thing Ren had said before walking away.
