This gallery should not have the age progression tag. First, the only scene where she noticeably changes is between pages six and seven, so it automatically lacks the presence rule. Secondly, what's presented isn't even an age progression, it's a time skip. Typing "nam troi qua" in google translate returns back as "years" in English. So I suspect a more realistic translation of the box in the top right corner of page seven to be something more along the lines of "5 years later".
