It was also my favorite show, the only 'Soap' I used to watch after Balika Vadhu (only till Avika Gor). I watched KRPKAB from Ep.1 and never missed a single episode. But lost interest after it became saas-bahu from love-story and finally stopped watching.
Not that much interested with Kasauti 2, but started watching from 4th Oct (only for Erica).
The only show I didn't miss a single episode is Jijaji Chhat Par Hain.
The other shows I watched for a long period are
1. Bahu Hamari Rajani Kant
2. Bhabi Ji....
3. May I Come in Madam
4. Kya Haal Mr. Panchaal
