Long before they showed Shiv's death in the serial they made it very evident to us through their promos...But again lets not forget, even though the character of Shiv was killed, Yash tonk was and still is a very integral part of the show as Samar...And even after Shiv died, they did show him almost all the time-although it was Shiv's soul and not Shiv himself...So the point is that those who love Shiv-Gauri as a pair is because they like Yash Tonk and Pallavi's on-screen chemistry...So Yash and Pallavi are still a part of the show-and in all probability will even get married...Even when Piyush was going to die they made it very clear in the promos much before airing the actual episode that it would happen....
Now for Milind-he IS the central character of the serial...Plus he has 2 women madly in love with him, his sister in deep trouble, his brother in law and uncle after his money and his ailing father....So how can they just bump him off....They have to be absolutely insane to do such a thing...Come on guys, let Nagpal show what he has to and give us high BPs..Ultimately nothing will happen to Michi...They are meant to be together forever...If they had to be separated, they could have shown the divorce...And plus with all this hype about Michi being the next big couple on TV, they will not separate them..So relax guys!!
