Yuuri. He is a safe choice. Nothing would happen. And not just because I play them both. Yuuri has lots of practice not getting caught when he doesn't want to be caught. And I think it would amuse her.
If she were choosing by some criteria like who she would actually be okay with lusting around with it would be Komui if he were still around and if not...Conrad. Not weird at all. /glances at Gwendal.
