Bad Apple

Yakov knew lectures were meaningless with Victor. He was no longer a figure of authority as far as Victor was concerned. There was only one person Victor really listened to now.
Yakov scowled.
Yuuri Katsuki.
Who gave him the right to barge in and conquer the heart of Russia’s greatest skater like he did? He always thought that Victor would find someone clingy who would be smitten with him and hang on his every word. He never expected it to be the other way around, even if he was as innocent as a child.
When Yuuri wasn’t around all Victor talked about was Yuuri. When Yuuri was there everyone else became background detail.
Yuuri was no good. A bad influence. Everyone could see that. People walking past him in the street could see that: the boy insisted on wearing leather and looking like a delinquent. Scandal followed him everywhere and he picked fights with everyone. What was Victor doing with him?
Apart from the obvious.
An AU were Yuuri is a very sarcastic bad boy and Victor is his very flustered and innocent coach.
