It means that the heroine doesn't love the hero and wants to break up with the hero.

The hero kept her and begged her not to leave.

So the heroine said, I want the emerald from Melbourne, and I won't leave if you give it to me.

So the hero borrowed money from Melbourne and tried to make money.

Finally, I saved some money and went to a jewelry store to buy jade.

As a result, the boss told him that there was no jade in Melbourne because it never produced jade.

The meaning of this story is.

The heroine told the hero with the emerald of Melbourne.

She can't come back to him, just as Melbourne doesn't produce jade, so she can't buy it.

Is an unchangeable fact.
