Jae-Ha Yoo

About

He is twisted, pessimistic, and cunning to the point where people find it difficult to be around or talk to him. He is also extremely petty and sly. However, he is still someone who would feel guilty and upset about his comrades if something bad happened to them especially if he played a role in it. But originally, he had no self-esteem and is regarded as an undisciplined and terribly honest idiot and pushover.
