Is there something wrong?

You don’t have to ask this question to her when it is really obvious. She will just lie to you. By the looks in her eyes, the tone of her voice and even her body language, you can already figure out that there is something wrong. Sit next to her. Put your arm around her and let her head rest on your chest. Don’t force her to talk because she will when she is ready. Just stay by her side. You mere presence is enough to comfort her.
