I don't think Sapna's crush on Dr. Shubhankar will last. So when maybe Sapna is heart-broken over Dr. Shubankar then Atul & Sapna might come closer first Atul can cheer her up and then Sapna will fall for his sweet character. They would be the ideal pair in this show...cause they are both sweet & caring.
The other possibility i c is Atul & Ritz. Armaan has started to fall for Ritz and i believe Angie also likes Armaan. So i am sure Angie will do something to not let AR get together. I also have a feeling that Ritz will think Armaan is playing with her cause he is such a flirt and she won't accept his love.
In that case, AR won't happen, and Atul does care a lot about Ritz...altho i have a feeling it will be a one-sided love from Atul's side. Everyone, including Ritz, Armaan, & Atul will realize that AR are the really in love with each other and Atul will stay silent with his broken heart and then maybe him and Sapna can be a balm to each other's paining hearts.
I would love Atul-Sapna jodi.
