In a romantic outdoor cafe setting, Akshay Kumar and Shilpa Shetty are affectionately cuddling and whispering to each other. Standing directly behind them, Suniel Shetty looks on with a stoic, visibly awkward, and uncomfortable expression, highlighting his role as the ignored third party in the moment.
This scene is the definitive representation of being a 'third wheel'. It is used to convey feelings of awkwardness, exclusion, sadness, or being forced to watch a romantic couple when one is single or feeling left out in a social group.
