The story is about the love and hate relationship between Shlok Agnihotri and Astha Shlok Agnihotri. If Shlok is a hot beam of the sun rays then Astha is a gentle moonlight that glimmers. If Shlok is an espresso, then our Astha is a creamy cup of latte. If Shlok is a gusty wind, then Astha is a breath of fresh air. Their very nature is completely the opposite of each other.
The statement Ek raat, ek roshini describes them well. Shlok has an extremely strong personality. He prefers the company of himself. Just like his emotions, he likes only dark colours, be it in his outfits, his room or any aspect of his life. He does not let in people into his life easily and thinks women are not at par with men. Astha on the other hand is a happy soul, she enjoys the company of her loved ones. Her life is filled with colour. She values relationships unlike Shlok.
