According to a review, this was inspired by love story (1970/book). I wasn't a huge fan of that movie, but according to said review, they don't have much in common other than a few plot points
nobody is perfect, not even our parents. sometimes they don't know how to express their love for their children.…
We are responsible for our choices, whether good or bad. But the way we were raised and the mindsets that are instilled on us still affects us and it's not so easy to change.
I still remember watching it while it aired
