Tall, muscular, tough exterior with a softer inside to people who are very close to him. Playful and humourous compared to Beom Geon Woo. Cha Chae Hyun is rather handsome and has a neck tattoo that makes him look like a gangster which Beom Geon Woo hates. He's a person to takes things into his own hands when his demands are not met or to his expectations. Don't underestimate or take advantage of his kindness... if you can earn it.
