Yuuri Katsuki & Lydia Martin
Okay, yes, Yuuri was fond of people who happened to be male. But he was also fond of people who were female as well. Which was why he told them when he signed up that he was fine with both men and women.
"It is nice to meet you, Lydia," he said, with a slight smile. "Four years is a long time to be somewhere. Do you like it here? What do you do here?" So he was full of questions. That was okay, right? It was only five minutes, so. He wanted to get to know Lydia as much as possible.
