Thank you.

this is not a font,

Yes, not a font. You could make your own if you have a drawing tablet and Livebrush.

Now wait a minute... How do you know? There are so many handwriting fonts. This honestly just looks like a handwriting font to me. I would suggest searching the handwriting section for a similar one, or one that you like just as much or more!

You know, guessitsash, you maybe right. Or not. Yet, the mere fact that it has not been IDed in two weeks is an indication ...
