He is a concept!
Barun was a regular next door boy working as operations manager. Yet, imagine the depth of his human relationships. A school-friend who ventures into tellywood gives up a show and instead passes Barun's photograph. When Barun makes relations, they are thick and made for lifetime. You realise this in every photograph of his. Whether it's with Sanaya or Aakash or Gautam Hegde. Daljeet Kaur while revealing about her personal tragedy in her IV after her divorce, takes Barun's name for being her strength.
This man has never had any professional training in acting; yet he can emote like very few do in telly wood! Imagine the sincerity of efforts that he must be putting in to be able to carry on a lead role. No khandani ( family) legacy to back him up. Yet he is the king of expressions, undisputed!
Even about his marriage! Imagine the situation that a girl is school topper, studying abroad and he has never been to any formal full time college. Yet to have faith in his own self and follow his belief/ his love with perseverance, so deep that he went abroad himself to propose to her. How much people management (family and outside), time management (BHPH was on), money management he must have done to reach her? No wonder, she said yes immediately and believes in his belief till date. Remember Arnav dialogue from first season kidnap track distant telepathic convo? "Tumne mujhe iss vishwas pe vishwaas dilaaya." (you made me have faith in your faith).
Last but not least, never ever does he talk about all this that he has managed in life. I have seen some such celebrity IV of chuddy buddy love. People talk about the strife they had to do, but our man never! What he mentions about that incident is her generosity. Now that's real love... Admiring your partner than just sticking to self. Absolute humility in this man! You have to put yourself in his shoes as a human being and understand the greatness of his life, his character. He won't speak it out himself.
