For what it's worth, I watched a fair bit of KRPKAB as well. Lost interest when there was more Vicky-Maami and the villainous stuff before the leap.
I actually liked this one particular promo of the serial A LOT.
Don't remember the exact one, but Sonakshi asked Dev whether his mother had openly said she disapproves of the relationship. He replies that she hadn't said anything of that sort, but he understood it.
To which she replied something like "Toh phir theek hai, main bhi kuch nahi bolti, tum samaj jaana", followed by the BG score.
Dunno why, but the promo stuck with me, and it was perhaps one of the reasons I started watching KRPKAB.
Obviously liked Shaheer and Erica, but I also watched it for Supriya ji- the few parts I watched of her in Saasural Genda Phool with Ragini were quite nice.
Edit- managed to get the YT link
