Make a story about Korean teenage girl named Choi Hyun-mi, she discovers a mysterious amateur radio that communicates with the past. It’s a small, simple old thing with a dial on one side and a speaker on the other, but she found it in an abandoned room at school and has no idea how it works. She was curious about the radio. She checked the radio’s microphone. “Hello? Is anyone one here?” Hyunmi asked.
“Hi! My name is <PRESIDIO_ANONYMIZED_PERSON> and I’m from Seoul, You probably don’t remember me.” a young man answered. The line cut off with a click. “Hello?” Hyunmi tried, staring at the receiver. Nothing happened. Her brow furrowed. Did she just miss something? She looked around at the room and saw nothing out of the ordinary.
