While the concept of "national crush" is subjective and based on popularity and public opinion, Manu Bhaker, the Indian shooter, has been referred to as the "national crush" in some contexts, especially after her performance at the Paris Olympics where she won two bronze medals.
It's important to note that this isn't an official title and other female athletes may also be considered popular and admired figures in India. The idea of a "national crush" often reflects a moment in time and can change with sporting events and public sentiment.
