Jonghyun's blood type is AB,Taemin's blood type is B, Key's blood type is also B,Minho's blood type is also B same as Taemin and Key and Onew's blood type is O
I can't remember but the last time I saw something about their blood types, it said: Onew was a type O Jonghyun was a type AB I think Key, Minho and Teamin I think were the same, I think they are a type B
