Face With Open Mouth Emoji appears when a person is shocked, a shock that isn't from fear but from surprise. In this, the face’s eyes are wide open, the mouth is round and completely open, and the eyebrows are in a balanced position. Unforeseen news, an unexpected truth, or a heartbreaking disclosure often trigger this emotional response. The facial expression indicates that the person is still searching for the right words. There's no joy, no sadness, just a stillness that shows that your mind is in fermentation.
