Setting Sun (слэш)

Canon-divergent AU. Just before he skates at the Hot Springs On Ice, Yuuri receives a photo of his drunken GPF banquet antics; consumed with humiliation over a night he can’t remember, he loses the competition. Victor goes back to Russia with Yurio, and Yakov comes to train Yuuri in Japan. One night, frustrated and miserable, Yuuri posts some personally relevant song lyrics on Instagram—and wakes up the next morning to find that Victor has posted lyrics that seem to be a reply.
With the world watching their every move, Victor and Yuuri begin trading lyrics in a secret conversation; from playful rivalry to intense seduction, through Savage Garden and San Fermin, their virtual affair unfolds, hidden in plain sight. But the Grand Prix approaches, bringing with it newfound opportunities for Yuuri’s career, and his new life hinges on two things: winning the gold, and staying away from Victor.
CHAPTER 21: Yuuri Katsuki will never know how powerful he is. He’s a lightning bolt, a piercing shaft of sunlight, a lighthouse beam cutting through the storm. He’s something great and powerful and awesome, in the ancient biblical sense.
