"...are 10 million yen worth of pure gold"
So, just 10 million yen? AKA 69k USD today (yeah, it's 69k dollars, or 69206.5 to be more precise).
What does the gold change in any of it? It is like that classical "what is heavier: 1 kg of feather or 1 kg of of lead?", but with money instead of weight.
Also, is 69000 USD so hard to get? It's the value of some cool houses or cars, which are not so rare to see around. I know she is only a teacher, but maybe she could, you know, try to be an actress again, get a loan or whatever, and pay 500 dollars per month for 2 or 3 decades (there are places in which things like that are pretty common, like when the government wants to help poor people to buy a home, so the family pays a lower price per month, but for A LOT of years).
I really should try more to avoid internet while sleepy. Not only I did came here to other thing besides jerking off, but I lost too much time reflecting on how people treat money around the world, and how they don't know that 1 dollar is worth 1 dollar only no matter if you acquired it by selling gold or by a regular job.
