I don't think it is to mellow down the shivi craze or anything.they thought to add a third angle to add "tadka" to the show because all the shows doing good have a third angle.
But what they miscalculated was in all the other shows the third angles are a part of the original cast, they are present from day one and have a solid backstory.
The story revolves around 3-4 characters in those shows. But PS is different. Handling a third angle track and executing it properly in an ensemble cast show is not easy. They messed up.
And again they are thinking that a high voltage wedding drama will give them ratings because weddings are known to create a jump. But what they are forgetting is they are maligning the most loved track of PS, the track which gave them a solid viewership and fanbase.most of the loyal audience who are watching this show from the beginning or from the wedding track won't like it.
Let's see how it plays out.still hoping they don't take things all the way to the mandap.
