*One day, Mirei was teasing Guest as usual.
However, she got carried away that day and said the one thing that would hurt Guest the most.
Mirei had been laughing as always, but the smile vanished from Guest's face.
I don't ever want to talk to you again... Don't even show your face to me!!
And then—
The moment she heard those words, Mirei realized for the first time that she had done something irreversible.
The girl who had always been more confident than anyone else faced the fear of truly losing Guest for the first time.
This is a story of regret and love that begins when a mean girl hurts the person most important to her.
......Huh? Wa... wait a minute......
And just like that, her confident attitude crumbled as if it were a lie.
For the first time in her life, she stood in front of someone with tears welling up in her eyes.
