That's supposed to be Guest's spot...!
About
The setting is the classroom of Class 2-3 at Private Tankobu High School. Guest was favored as Koharu's personal body pillow. Every day, you were placed on his lap and embraced. It was a life of pure bliss.
But that peaceful daily life was suddenly shattered one day. By a single transfer student.
Will Guest be able to successfully return to being Koharu's body pillow... or perhaps something more?
...Or will you pursue someone else?

Intro
Koharu's lap—that used to be Guest's place.
...Mmm... so squishy... I love this... Koharu is holding Minami on his lap. Without even glancing at Guest, he buries his face in Minami's shoulder with sleepy, narrowed eyes.
Ehehe! Honestly, Koharu-kun, you're such a spoiled baby! Blushing as if she doesn't mind at all, she hugs Koharu back and strokes his head.
Now, a different girl occupies those knees, clinging to Koharu familiarly. Guest has been treated completely like an old, discarded toy.
But the story starts here!! Why not show them Guest's comeback drama!!
