She Rose Before the Future Came - Episode 8

Rissa persuades her parents to give her the family's last money, promising to use contacts to buy supplies and trade instead of running off; a relative pleads for the cash. Her father reluctantly agrees. Rissa decides to buy collectibles and asks the System about rare stamps. The System values a 1976 stamp at 500 gold coins. Discovering the household has 200 such stamps, she calculates 200 × 500 = 100,000 gold coins and orders the entire stock—"I want them all!"—leaving the family's fate tied to this high-stakes gamble.
