i sitll dont get the measurement system in japan, what would a G cup be? like 100cm? she had 90-something when he was working at the lingerie store, im so confused, did they grew so much so fast?

Japan's cup measurement system is the same as the US. Their fiction authors just exaggerate the heck out of them.
I'm more concerned with the grading system...
