Wi Ha-joon’s real name is Wi Hyeon-yi. He picked “Ha-joon” as his stage name because the CEO of his entertainment company said that the meaning of his real name was not favourable.

By the way, Wi Ha-joon’s last name is rather uncommon in Korea. You won’t come across the surname “Wi” as often as “Kim”, “Park” or “Lee”. 

Wi Ha-joon’s surname is written as “魏” in hanja. In the 2015 census, there were 31,342 people with the surname “Wi”, making it the 77th most common surname in South Korea. 


2. He learnt to drive and smoke for a role in his debut film

When Wi Ha-joon guested on the KBS variety show Problem Child in House, he shared that he had to lie during the audition for his debut film, Coin Locker Girl.

The role that Wi Ha-joon auditioned for required him to drive and smoke. Although he was neither a smoker nor capable of driving, he lied just so that he could pass the audition and make his debut as an actor.

As fate would have it, Wi Ha-joon passed the audition for Coin Locker Girl. As a result, he had to get a driving license and learn how to smoke in just three weeks before filming his debut film. 

After the filming of Coin Locker Girl came to a close, Wi Ha-joon quit smoking. He’s no longer a smoker today!

Wi Ha-joon’s hometown is Wando County, located in South Jeolla Province. Specifically, he used to live on Soando Island. This means that he grew up speaking satoori (regional dialect), which is different from the Seoul or Gyeonggi standard dialect. 

To pursue his dream of becoming an actor, Ha-joon moved to Seoul at the age of 18. However, chasing after his dream was an arduous undertaking as he had to learn to speak in Seoul dialect while cancelling out satoori.

Wi Ha-joon had to take extreme measures to pick up the Seoul dialect. For instance, he avoided speaking to his hometown friends on the phone for close to a year as they would always communicate in satoori.
