Roshni's small ideas of testing with sweets etc mayn't work b'coz Sid may not reveal himself like that.. She needs to do something big.. So suggest what Roshni can do, to make Sid spill the truth
I think, something like Roshni getting hurt or her doing some drama of getting hurt or a suicide drama like the time of Misha can make him spill the truth.
Or else she can act like falling in love with Raghu and accept him to get marry and instigate the Sid in RaSi so that he may get angry on her and blurt out the truth😆 But there is less chance that he may believe Roshni's drama😆
So, what are ur ideas about how Roshni can make him say the truth..
