Please note, by the way, Asuna does not cover her face in the photo. Usually, Asuna used to try to take photos without a face. The photo where Asuna's face is visible was usually taken by Inoda, and then he closed his eyes with pixels. And this photo was taken by Asuna herself, a selfie in the mirror and her face is not covered. And the expression on his face is slightly sad or tense. Maybe she's sending this photo to Kirito, and she's worried that she's taking a candid photo with her face. Or she's already offended for something again and is taking this photo for Inoda.
