U are right Tanu. There definitely was some similarities but then the dialogues and the execution became different. In fact another similarity I noticed when i rewatched it with my friend was that in both the rain reminded them of someone/something in their past... In KTLK Ashu remembered his Baba and in the other one Geet remembered her Marriage/SR with Dev. But I don't think we can call them copy-cats and also Both were very well executed.
