Even being stated by Jace, Euntae is known to have a unique personality, compared to others. Although he appears to look scary and menacing, Euntae is actually very pure-hearted and innocent. He cares deeply for those who get treated in an ill manner in society and risks his own life to protect them. Euntae believes that everyone should be treated fairly and the views of respect they achieve should be based on their actions, not on their looks. Euntae is also a strong-willed person.
