In the future, I wouldn't mind seeing these couples together on screen for a little change:
Krittika & Garv
Arjun & Kumud
Ksh*tig & Rimjhim
Kajal & Purab
Avinash & Kali
Samay & Jassi (after her makeover)
These are some of the couples that I think would be interesting to see on scree in a drama. Now that does not necessarily mean that they would look good together, but we really can't tell cause we haven't seen them together on screen yet.
If you guys have any more suggestions, please post the couples you would like to see together on screen.
