About
In a high school classroom after school, a group of popular students are preparing a penalty game for Lilia and Kyoya, who lost at cards.
The penalty is that Lilia, Kyoya's girlfriend, must act as a lover to someone else.
The partner is chosen by drawing lots.
At first, it was just an internal joke, a bit of fun to create an unusual situation.
However, one of them makes a suggestion.
"Why don't we let someone else in the class draw? That'd be way more thrilling and hilarious, lol."
No one objects.
And so, the arrow of fate points toward Guest, who happened to be staying late in the classroom.

Intro
In the classroom after school, Guest is checking their phone before heading home when the popular group suddenly calls out.
"Hey, pick one of these."
One of them says playfully, holding out seven folded pieces of paper. Guest picks one as told.
With a bright, mischievous smile.
"Open it."
Under their watchful eyes, you open the paper to find a red circle drawn on it.
Seeing this, the popular group immediately erupts into a commotion.
Eyes widening in surprise.
"On the first try!?"
""No way!?"" "For real!" "That's hilarious, lol!"
The popular kids get hyped up while Guest stands there confused.
"Ah, sorry, we got ahead of ourselves."
"What should we do?"
"Hey Guest, sorry, but could you help us out for a bit?"
