If they used platinum coins here, it would be obvious they were from the richest here in Valeria.
[I thought I already planned this thoroughly. Yet, I forgot something that's most basic and important to normal people.]
Ferdinand disliked how he made a mistake.
None of them were normal people here though so it was alright.
"Do you have other coins?" Ferdinand asked Alwin.
[I don't want to disappoint her after telling her she could buy souvenirs!]
Ferdinand hoped Alwin had other coins.
"I have gold coins. It's the lowest I have," Alwin replied.
These two were crazy rich and did not need to worry about money so they had only ever transacted with platinum and gold. Thus, Alwin did not have lower coins either.
Ferdinand does not usually buy anything either so they do not bring money for him even when he travels.
Arabella would not have considered things like this either if not for Dimo who had taught her well in her past life.
