Raghu's character:
Cold exterior with a very warm heart.
Dislikes women being treated wrong.
Likes kids and keeps his promises.
Kind to people who show him some respect.
Adored and respected by his friends.
Although he is considered as a gangster I would say he is more like Robin Hood, since he prevents harm from coming to his street and the people who live there.
He may have the exterior of a gangster but his heart is purer than pure.
He's definitely falling for Antara.
And what I like about him is he tries to do the right thing.
