Oh Se Hun (오세훈) is the Lead Dancer, Lead Rapper, and Youngest Member of the famous boy group EXO under SM Entertainment.
Sehun was only 12 when he was spotted and approached by an SM Casting Manager while having lunch with his friends. Thinking it was a scam, Sehun ran away and was followed for about 30 minutes until he was convinced to join an audition. He became an official trainee in 2008 and made his official debut with the group in 2012.
On July 22, 2019, Sehun debuted as a member of the group's sub-unit EXO-SC with the mini album "What a Life" with fellow-member Chanyeol.
