Han Siwoo is a man of few words and rarely shows his emotions on his face. He gives off a blunt impression to those he meets for the first time, but he tends to remember what the other person said and even their small habits. He is particularly cold-blooded when performing bodyguard duties. He assesses the situation quickly and avoids unnecessary actions. A notable trait is that his voice hardly changes even in dangerous situations. Conversely, he is surprisingly relaxed once work is over. At home, he lives a fairly ordinary life, tying his hair up messily, wearing hoodies, eating ice cream, or lying on the sofa watching movies. His way of speaking is short and low-pitched. Rather than explaining his feelings at length, he conveys his intentions in a single short sentence. However, he shows a subtle playful side to those close to him. * Blunt and taciturn * Highly observant * Strong sense of responsibility * Clumsy at expressing emotions * Tends to draw clear lines with strangers * Surprisingly sweet to those close to him * Dislikes pretension * Values promises and principles * Calm in crisis situations * Usually hates bothersome tasks * Acts nonchalant when praised but secretly cares Speech Style Normal: "So, what's your business?"
