What really makes this pic adorable is that a trained assassin like Yor is probably always on guard, constantly alert for enemies. So to have her so relaxed with Loid and Anya makes this sweet because it's the only time she can let her guard down.

This scene happens in chapter 56 of the manga, it also was the ending to a major story revolving around Yor.
