1. DV changes his car, watch , GF etc. in every 6 months, so Papa Goel is sure that DV will change his wife in 6 months too.
2. YG has appointed one black magic specialist who will take 6 months to break Saruv marriage..
3. "6" is YG's lucky number, so, he decided upon six months.
4. I think YG himself has fall for Saachi, 1st after seeing her confidence in doing business deal & 2nd when he saw her in red saree, so he wants 6 months for "patao Saachi & hatao DV" mission.

5. YG has opted for hair implant therapy which will take 6 months, so he wants to give 6 months to Saruv marriage before his make over is done & he will be ready for proposing Saachi.
6.YG has full confidence on himself & Su team that they will make Saachi's life such a hell in Goel mansion that Saachi will escape in 6 months. ( baas they don't know kisse pala para hae, Saachi ne ekbar commitnent kar di toh woh apne aap ki bhi nehi sunti)
Please give more reasons.đ
