假微笑

'假微笑' translates to 'Fake Smile'. This indicates that the user may be wearing a smile on their face, but it does not represent their true emotions inside - suggesting they might be sad or unhappy underneath their cheerful appearance. This is typically seen when a person forces a smile to hide feelings like sadness, discomfort, shyness or awkwardness, etc., showing their internal struggle between reality and exterior self.
