Food + Transportation — 300,000–500,000 KRW per month

Honestly, food costs in Nha Trang are almost non-existent. You can eat your fill of a bowl of local pho for 30,000 to 70,000 VND (1,700 to 3,900 KRW) or a banh mi sandwich for 20,000 to 40,000 VND (1,100 to 2,200 KRW). You can see many shops selling banh mi on the streets.

For transportation, I mainly use Grab motorbikes. A trip within the city costs around 12,000 to 40,000 VND (700 to 2,200 KRW), which is practically free compared to Korean taxi fares.

Combining food and transportation costs, I come in within 300,000 to 500,000 KRW per month. That is less than spending on food alone in Korea.
