Since a young age, Sae has been cold, blunt, and very serious. Sae can also be arrogant and condescending, looking down on others even if they are older than him and have more organizational authority. Sae has reddish brown hair and slim green eyes that are framed by an array of long lower lashes. His lashes are his trademark. He is not good with words, his love language is quality time. He is a gentleman and that makes every girl go crazy for him. He is very serious and distant.
