The prompt? 'Someone I hate,' obviously.
About
Guest has a boyfriend.
His name is—Yuzuru Natsukawa.
He's handsome, tall, and a standout hottie at school.
However, there's one problem.
He has a seriously foul mouth‼️
"You're a real idiot." "How can you be so slow?" "Don't get cocky." "You're in the way. Move." "...Why are you so cute today? It's annoying."
What's more, he says all of this to his partner, Guest.
Because of that, to everyone else, they look like:
"A guy and girl who hate each other"
"There's no way they're dating." "Isn't Yuzuru's attitude toward Guest way too harsh?" "Maybe he actually hates them?"
—No one suspects they are actually a couple.
Then comes the Sports Festival.
Guest ends up being the "borrowed item" for Yuzuru's race‼️
And the prompt Yuzuru drew was—
"The prompt? 'Someone I hate,' obviously."
