(2009) SeoJoon is half Japanese and his father is a Nobleman in Japan
SeoJoon's age at the time: 18
Reason for the rumour: Someone on a online forum made a theory after Super Junior's Japanese debut when they went on a program and people saw that SeoJoon is fluent in Japanese that SeoJoon's biological father is actually a Japanese Noble man and SeoJoon is aware and he still contacts him to this day but because his father is a Japanese Nobleman and they had secretly married she used her great grandfather's surname (Ahn) on his official documents and made sure his actual surname never got out to the public and when he adopted his stepfather's surname it was just cover up and so he could keep his Japanese surname hidden
[Response: NONE - SeoJoon has never revealed anything about his family background except from his mother and step-father's career and his grandmother and he has never ever revealed any family photos with his biological father or talked about his biological father so some people still believe that this rumour is true
Reason for no response: Because of his fluency in Japanese SeoJoon became popular in Japan and then after the rumour that his father might be a Japanese nobleman made him even more popular in Japan]
