Were you born in Korea or were your Birthrelatives

Hey there!I have come across this forum during the search for bio mum or family on behalf of my partner. I have his permission and whilst his curious to learn more about himself and family, he has not attempted, and I would say for the reason of how emotionally taxing it must be as most of you would know. I’m hoping I can do the work and searching for him in the background and provide him with the opportunity to reach out and connect with relatives if my search is successful. He was born in Seoul, South Korea in 1984. He was then placed up for adoption shortly after and brought here to Australia. Birth mother’s name was Kim, Mee ja. DNA testing has shown no matches, and no results when you search both his bio name and mother’s name on sites and forums such as this. What else can be done to help make that connection? If bio mother is not looking for him. Currently I’m just trying to put his name and her name out there on as many platforms as possible and hope the reason she has not is due to obstacles or fear of rejection and show that the connection is wanted/welcomed.
