KDPfan, your tracing/analysis of the present Rishali and Risha situation is perfect. Even after KDP ended Rishali were going well together. Remember, even during that visit by her to promote jewelery with Pooja from Lokmat, she was so excited to tell her fans about the joint new project (probably about that webseries). So it coudn't have been raat gayi baat gayi like LP PM, immediately after serial ended. It was only after Sayali's London shoot we found that Sayali stopped responding to Rishi's insta posts.
I too now feel there is a possibility that this Risha is only a publicity stunt and nothing serious. Trying to grab attention. Maybe even his entering "best men contest" with body building pics everyday could be one way of getting attention in the industry.
The possibility of Isha suggesting all these tricks is strong (IMO) because she is more of a showy character than the low profile Sayali.
@aekiel, Isha is Isha Keskar, aka Banu of Jai Malhar.
