[Parent-Child DNA Test] \"I am full of hope that tests like this will bring more happiness to the world\"

Thank you very much for your help this time. My son is divorced, and because his ex-wife had also been having an affair (which she confessed herself), he was worried about the blood relationship with his child.
I am very grateful that my son's doubts could be cleared up. I am full of hope that tests like this will bring more happiness to the world. Thank you very much.
