La will be at the spa and either her pimple will burst and she will have many small pimples in its place or this pimple will end up being chicken pox and so she won't be able to accompany asr to nainital.
Now nani will not let asr go alone because of his sugar issue and will tell khushi that she must go with him.
At nainital, khushi will sprain her ankle and asr will have to carry her into the romanticly decorated room and place her on the bed.
Or there will be wine and khushi will drink that and we will get many rabba ve scenes.
Please add more scenes that u would like to see if khushi goes to nainital.
I am very hopeful that she will go and so their love story can move forward!
