do me a favour

hi guys,
am new to saathi re forum..can anyone tell me wat happened..actually suman loved prem(arjun) na..wat happened to him..how come suman is paired with rajeev now...

Suman actually causes Prem to have an accident and they fall for each other when she keeps visiting him in the hospital.
Unfortunately, Prem has to leave for America for a year to do his studies and they are unable to talk about their love/ marriage to Suman's parents beofre he leaves.
The matter is still a secret.

Rajiv's family and Suman's family meet while on a pilgrimage and Rajiv saves Suman's life from a fire.
He falls for her and Suman does not realise this.
Suman's family is now attending Rajiv's sister wedding where all this confusion is happening.

god..once again lovers get separated uh..i started watching this show forarjun.but he is out of the show

can u plz tell me on what days does sathi re come
