Chanchan and Kaisa Yeh Ishq Hai

Has anyone noticed that these two shows have a similar storyline? Both Chanchan and Simmi are modern and have to adjust to a more traditional, old fashioned family. Also both of these almost have the same current track e.g in Chanch chan has to deal with Dada Ji and her family was worried and in Kaisa Yeh Ishq Hai the family is worried about Tau Ji's sister coming. BTW im not saying anyone is copying anyone.
