Precap:
Yash says to Arti that soon the sadness would be over, and he would bring a smile back to her face again. arti says NOT TO bother about that. Seeing arti so hard trying to cope up ...for her sake, Yash thinks that he should tell arti that his important work is regarding ayu.
Now why do I think that Yash will indeed share this with Arti and together they will try to see what Ishita is upto...that is after Arti disclosing ALL to yash...(love letter in blood)...this tie-up..they may not reveal...and even viewers will be kept away from this...lets see. hoping to see a different route that reaches the destination soon.
