I agree with you all. I have a very bad feeling the rope drama will occur after the song sequences. One of the segments did mention that Viren utilized time and the fact that that NivRen were home alone to its full potential by having the photo session affair. And today, while taking Nivi towards the room, Viren did mention that no one is at home. So yeah logically speaking, the song sequence should follow this.
Also, in the precap, Divya is the first one to see Nivi fiddling with the rope which clearly means she's at home. Further, the entire the Sood Parivaar is gonna gather around soon in the room so that indicates they're all at home 😭 It follows, then, that the rope fiasco is scheduled to be held after the song sequence. And it sorta does make sense because I doubt Nivi or Viren for that matter will be in any mood to be dancing around after the shock.
