I chose to separate Nadiya and myself for various reasons, turning Nadiya from my sona to main character/mascot of mine. The main reason is that as I did confirmed they were the same age as mine for the said series more than a year ago at the time of the production. But, as time passes without any fresh development progress for my canon series, there is an age difference, which is why I chose to do that separation.

There's not only the reason that has the difference, but there's also some other difference between me and Nadiya as well, like the information, likes, dislikes and more.
