This might be because of weight loss or mewing. So me and a couple of other guys were looking through a yearbook and were making comments on their appearances. And he said "Fred's face is the only one that has changed."
There are only two reasons I have in mind. 1. Hormal changes: weight loss and, or facial bone structure changing from hormones. 2. Mewing and chewing.
It was late in age 13 and it was after weight loss (it was only a few pounds).
Let me know what you think.
Just puberty
