Peheli Mulakat

Regarding the night walk of arjun and arohi episode.

I doubt why arohi have forgotten about their 1st meeting on the train.She comes to know that it is arjun punj compartment through one of his managers.I think that is their Peheli mulakat.Have arohi forgotten about it.

Also arjun listens to arohi's song on the train. Have they forgotten about this.Why dint they come out.Have the directors forgotten?????????????
