Notebook Movie Inspired/Copied from The Teacher’s Diary

The movie Notebook starring Zaheer Iqbal, Pranutan Bahl and produced by Salman Khan Films seems to be inspired/copied from the Thai movie The Teacher’s Diary. Not sure if its an official remake but I don’t see any credits for the original movie. Here is the trailer for The Teacher’s Diary.

And here is the trailer for Notebook which is very similar.
