When Raghav said he was 32 I was like yeah .. I am tired of serials where they show self made business tycoons who are barely 20 . Come on it takes time to finish studies and make name for yourself (baring some few in Internet world) . Rahgav is shown to be 10000 crore guy in construction world .. Arrogant, has attitude, very sure of himself, very set in his way, commands respect .. His age is perfect. 20+ guy showing this attitude comes as a show off .
Raghav's age is ok, now comes Kalpi and her age .. They could have shown her little older, maybe 25/26, but then it would not work as they had to show her as rookie , initial stages of her life ,, flunking inexam(I know , I know CV's seems to have forgotten) etc. so her age of 20+ is also reasonable
Now we have a couple, who seems to have a bond since childhood and compliment each other now. even though Kapli has not confessed, you cannot forget the fact that after being really illtreated , it just took a heartfelt apology and explanation from Raghav for her to forgive him, she went back next day, not just as an employee but as a person wiling to share his life - remember that's what he asked on phone. She feels the connection with him and wants it too, just scared because of the difference in statu, experience and age too :-)
My point is When people are connected , age should not matter
