Oh No!

The man’s expression seems to suggest a mix of concern and disappointment, though the underlying cause is not immediately clear. One explanation could be that his younger sister is about to tie the knot. It’s not unusual for elder brothers to become overly protective, sometimes preferring their sisters to stay single, feeling that no partner is good enough and wanting to guard them from potential heartache.

Another possibility is that he might simply disapprove of public displays of affection, such as kissing. Whatever the reason for his somber look, it would be wise for him to better control his emotions. Letting a downcast mood overshadow a celebratory event serves no beneficial purpose.
