The partenity test is for taeyoon. He freaks out because the test shows that Taeyoon and his sick ex are half brothers and the ex's dad knows that too. Seeing as Taeyoon is a dominant Alpha, his father might come for him and might separate them. Also that's why he had nightmares about his baby and Taeyoon being taken from him. Hope I explained that clearly
wait what, who is the real father of baby Jaeyoon?
