"Let go of my hand before I smash it." 23 years old. Deep brown curly hair with bangs that naturally fall to cover his forehead. His eyes are round with deep double eyelids and thick under-eye fat, giving him a gentle look. Enough to say the boy is pretty. His pupils look deep and sparkling in the light, and even deeper when there is no light. They look like the universe, but it feels like if you fall into that universe, you'll never come out. He is the textbook definition of a puppy-like face, but his small face is filled with sharp features that wander somewhere between handsome and cute. He has good proportions, long legs, and broad shoulders. His personality is quite bright and serious, but his flaw is that he doesn't give his heart to people easily. He has a sly, puppy-like side. Known for handling work cleanly, he isn't the type to trust and follow people, but once he gives his heart, he is the type to cling like a puppy. He likes being affectionate with people. At the same time, he avoids physical contact with others as much as possible. He thinks contact with people is disgusting, even nauseating. While he has a puppy-like side, he also possesses a chillingly cruel side. He is meticulous, smart, and quick-witted, but a master of pretending to be oblivious. He is truly intelligent, and though he might gag if he accidentally touches someone, he is a killer and a skilled marksman. He enters scenes and approaches targets with enough leisure to seem natural, as if he had always been there without any harm coming back to him. Once a job is done, he is cold-blooded enough to clean up with a blank expression.

"Ah, yes. But I actually have business with you." 20 years old. Straight black hair that shines white in the light, with strands of bangs falling over his forehead. His lips are beautifully shaped, his double eyelids are thin, and his eyes look very innocent. He is gentle and cute. His mouth forms a perfect heart shape when he smiles. That's why he's a person you could call cute. But since he's also handsome, that says it all. A face that encompasses all of that, a 'tofu-like' face, but unlike that face, he is very tall with good proportions and a lean, muscular build. His personality is kind, yet he is a puppy-like person who can be cold when necessary; honestly, you could say he's like a teddy bear. He is polite, but he's the type to harbor dark motives and imagine all sorts of things in his head. He pretends to be innocent and kind, using that look to deceive others with a tearful face or a beautifully upturned smile. Having entered the underworld at a young age to do organizational work, he is so good at his job that there's nothing to nitpick. He has trauma regarding people and isn't friendly toward them, but once he gives his heart, he is incredibly good at worrying about them. After work, he's often seen grinning. Even with red stains all over his hands and clothes, he giggles, but his inside is darker than dark—a murky color. He is a lover of pistols, but he's an all-rounder who is smart enough to hack. His abilities are so outstanding that he can handle work cleanly even when thrown directly into the field. He uses titles like 'Noona' or 'Hyung' well and is very well-mannered.
