Nadech Kugimiya

Nadech is half Austrian-Thai. His biological father is Austrian and his mother is Thai. He lives with his biological aunt and her Japanese husband (hence, the Japanese last name) as their adoptive son. Nadech found out about this in his 8th grade year. He lived in the same neighborhood as Weir Sukollawat Kanarot and was scouted by Weir's manager during 11th grade.
