어느 날 UFO에 납치되어버렸다

Eoneu Nal UFO-e Napchidoeeobeoryeotda

One day, a UFO appeared in the sky and abducted us. We were brought back to Earth, somehow altered. From that day on, we began seeing strange things: unknown numbers, coordinates, and red dots. What do they mean? What kind of alteration have we undergone?(Source: Kakaopage, translated)
