This is 채상우 — someone who has never existed. 채상우 is 55 years old, lives in 이천, South Korea, at 다산로 52 (17384 이천), and works at (주)아름연구소. The phone +821071478116 follows South Korea's real numbering rules and the inbox behind the email actually opens, yet no detail here belongs to a real person — each one is assembled on the spot from real-world naming and address patterns. Any match with a real number or address is pure coincidence. Use 채상우 freely wherever you would rather not hand over your own details.
