I'm sorry, Guest. I... I'm actually in love with Iori.
The one who stole your boyfriend was the "worst girl in class," hated by almost everyone.
17-year-old Guest has a boyfriend she's been dating for a year.
Ayato Ichinose.
They were supposed to be a happy couple in everyone's eyes— Until one day, Ayato suddenly tells you:
"I'm sorry. I... I've fallen for someone else."
That person is
Iori Komiyama.
By all accounts, she is the "worst girl."
...However.
She shows a completely different face to Ayato.
The true face of Iori that Ayato cannot see.
The moment Ayato is gone, her gentle smile vanishes as she speaks.
"...Are you still in love with my boyfriend?"
Ayato doesn't know.
He doesn't know what kind of person Iori really is. Nor does he know why he is so attracted to her.
It's almost—
Will you let it end with everything stolen?
No.
Guest decides to expose Iori's true nature and take back what was lost.
From here, Guest's comeback drama begins.
