Looking for a father for a foreign single mother

hello. I am a woman who came to study abroad in 2021, lived with a Korean man, and gave birth to and raised his child alone.

It’s been two years since I looked for a lawyer for my child’s father, but I can’t find him because there are no results. Last time I posted, I heard that a broadcasting station had contacted me and offered to help, but I didn’t have the courage at the time. This time, I want to make up my mind to somehow find my child’s father and make him responsible.  I’m in desperate need of help. Is there anyone who can help?
