Japraine: Lie Detector
Japan didn't know how he ended up in that situation. He was still trying to process it.
He had gone to visit his girlfriend, Ukraine, and was surprised to see her brother and sister there. Of course, he had tried to flee when he sensed the tension in their posture, but he didn't get far. Belarus had tackled him and Russia held him down while he was being tied to a chair. And then he was strapped to…
A lie detector?
"Alright then," Russia said cheerfully. "Let's start with a few basic questions to see how you speak. Favourite colour?"
Japan was confused, but told them anyway. They continued to ask a few basic questions, like what his favourite food was or even what the colour of his underwear was (apparently they wanted to see what his response would be when answering an embarrassing question). Japan didn't understand what they wanted.
And then they started asking questions about his relationship with Ukraine.
There were parts where Japan became really embarrassed, like when Belarus asked bluntly if they had had sex yet (the answer was 'no'), and Japan wondered if his embarrassment would make it difficult to get an accurate reading.
Finally, they came to what they said would be the last question.
"Do you really love Ukraine?" Russia asked.
"Yes," Japan said, calm and sure. "More than you can imagine."
Belarus looked over towards the lie detector and arched an eyebrow in surprise.
"He's telling the truth," she announced.
…
Ukraine arrived much later, and she seemed surprised to see her boyfriend having a cup of tea with her brother and sister, and while Japan seemed nervous, the other two were completely calm, and weren't even trying to threaten Japan.
"I'm sorry I'm late," Ukraine said, going over to hug Japan. "My boss kept me really busy with work. I'm happy to see you getting along, though."
Japan blushed and nodded his head.
When Ukraine asked them what they did the whole day, they simply replied with 'talking', though Japan seemed particularly nervous about the subject.
Ukraine might want to ask him when her younger siblings weren't around.
The prompt was 'Person B being hooked up to a lie detector by a distrusting relative of Person A. Their last question asks something along the lines of if they truly love Person A. Person B's response of "More than anything" displays nothing but truth on the machine in front of A.'
I originally wanted to use a pairing with Russia where Belarus hooked the other up to the lie detector, but then I remembered I had this pairing, so Russia and Belarus worked together. Because I think the two of them would definitely team up and be protective younger siblings, considering Ukraine's personality vs their own.
