I like the end twist which makes this movie and concept unique but at the same time when boy feels some guilty, go back to the girl at airport with rings,,, both boy and Girl just look at each other... That's more Unrelastic scene in this film,, it's justified that it's made out story to make girl and boy apart from each other.. At the same time this movie kind a stupid... If anybody doing so much in between.. But at the end they're don't even talked about that's very immaturity.... As per audience like me... It's really justified it's title 'Sweet and sour'... And kind a irritating ending...
