Nah Seohyun seems the type to be too busy with the dog to even care about the guy. We all know she prefers cute animals over guys.
And also from what has been said, she talks a lot in private, so I don't think you could say she's too timid to say anything. Maybe she is the one that opposes, it never said she agreed with the dog being there even though she let Tiffany keep it. But she seems to love everything so I don't know.
But why are we talking about Seohyun in the the Taeyeon thread?
