Honestly, only sharica knows what's happening between them but there is also a possibility that this remains one of the unsolved mystery for the longest of time.
I think its better for all of our hearts just to concentrate on devakshi but one wonders especially when there are so many coincidences that it becomes difficult to consider them as mere coincidences anymore.I mean once or twice can be coincidences but so many times, no...I don't think so.I feel too that something is definitely cooking between them but sharica are so confusing and they have kind of PhD in misleading fans so fingers crossed and praying for my shipper heart
I think they aren't coming out in open for now as they are working together and media will blow things out of proportion. If they admit to be in relationship, chances are focus will get diverted from Devakshi to Sharica which is not good for TRP of the show. Also Shaheer has a huge female fans following so it might work against his popularity.
Also then in every SBS or news segment, reporters might continue ask them personal questions which I am sure most people are not comfortable answering. I strongly feel that if they are in a serious relationship, they will admit it after the show ends.
