How to Lose a Guy in 10 Days (слэш)

“Let’s make a bet.”
Yuuri’s face falls flat, “a bet?”
“That guy. You don’t think you can get a guy to stay with you for a week? I’ll raise you ten days and I guarantee you can’t get rid of him. You can do whatever you think it takes to get him to ghost you, dump you, whatever, go crazy. Up your personality to 1000%, but I bet you can’t scare him off.”
 
Viktor tried to protest, “this is ridiculous, Chris, I’m not-”
“Ah ha! Perfect!”
Viktor stepped forward and next to Christophe, “where?”
Christophe gave him the knowing side eye and nodded in front of himself, “Asian cutie, straight ahead, blue tie.” When he saw Viktor’s reaction, he plucked his glass from Viktor’s clutches and went to walk away, but not before saying “I’m just gonna go talk with Mila. Make me proud, Vik. And remember, you have to make it last a while! Don’t let the media control your love life.”
 
Yuuri does everything he can imagine to turn this guy off, why isn't it working?!
