Are we looking at the same gif? lol
While I'm aware of the things between Juri and Shun, I didn't really think she ever put more focus on Shun than on Toma here. She is sitting at an angle, nestled in to the corner of her chair and her hands dead center. Her look to the side, I don't think was at Shun. I think it was just a look to the side.

Hoooowever, there is a split second where Shun IS looking at Juri.
