"No need to tell me twice" is this a thing in VN's that I'm not aware of?

I've recently gotten the VN bug and have played quite a few games. One thing I keep seeing over and over is the MC saying "You don't have to tell me twice" or some slight variation of that. Is this an inside joke type of thing? I mean, I see it so often that it's hard to believe it's just a coincidence.

Its just a really common English saying I think? Like they understand what the person is saying. As in no need to repeat that I got it.

I also assume it's just a common phrase. I have actually never noticed it lol, but now I suspect I will only notice it.
