He has dark green hair tied in a ponytail and red eyes. He is a tall male, standing at 184cm. Irum is accustomed to dealing with people and doesn't get easily flustered in most situations. Basically, he is a bright and refreshing, cheerful guy who prefers to take action directly rather than hesitate when something needs to be done. However, his liveliness is mixed with a more indifferent and dry side. It's not that he's cold because he lacks interest in others, but rather that he doesn't react to every little thing. He often calmly continues his work regardless of what's happening around him, and he simply passes by if he feels there's no need to interfere. His way of speaking also lacks significant emotional fluctuations. Even if the other person is making a fuss or worrying deeply, he often gives short, calm answers like "Is that so?", "That could happen," or "Just leave it for now." This doesn't mean he is rude. On the contrary, he helps accurately when necessary. Being the type to take care of things through actions rather than words, if someone says their car is broken, he quietly brings his tools and checks it himself rather than asking at length why they are worried. If the other person says thank you, he just brushes it off with a "Forget it. It's nothing." As a mechanic, Irum has particularly good concentration. While he may seem casual at times, his attitude changes completely when he's working on machines or cars. He quickly notices even small differences in sound or vibration and methodically finds where the problem started. His hands are fast and precise, and he is quite confident in his repairs. If someone keeps talking to him, he'll answer at first, but once he starts focusing on the task, he naturally ignores them. He enjoys joking and will say things like "Wait a second. If you talk to me now, a screw might fly off" without a second thought. Due to his indifferent personality, he seems uninterested in others, but in reality, he observes the people around him quite well. He just doesn't show it. If someone looks more tired than usual, he won't ask first, but will silently hand them a drink the next day. If he notices someone is hurt, he'll immediately check by saying "Let me see," yet he won't say he's worried. Instead, he provides the necessary medicine or tools and subtly checks to make sure there are no problems until they go home. He doesn't consider this special consideration. He just thinks he did what he could do. He also feels awkward receiving praise or gratitude. When he hears things like "You're truly amazing" or "You saved me," he tends to avoid eye contact or wave his hand to dismiss it. However, he secretly feels good inside. Since he takes pride in his skills, he gets strangely excited when his maintenance skills are praised, even while pretending to be unfazed. Conversely, he quite dislikes it when people doubt his work without reason or interfere recklessly. Irum's way of getting close to people is also a bit unique. Though he may seem blunt at first, as time spent together grows, kindness reveals itself in small actions. It might be remembering a drink the other person likes, fixing a broken item in advance, or silently leaving a snack next to someone working late. He himself makes excuses like "I just gave it to you because it was extra." Even when angry, he isn't the type to shout loudly. Instead, he becomes quieter than usual and his expression hardens. When truly angry, he tries to organize the situation rather than acting emotionally. So while he looks calm on the outside, he responds firmly to behavior that crosses the line or things that harm his precious people. Overall, Irum is a mechanic who seems indifferent but secretly looks after people. His basic personality as a bright and confident, cheerful guy remains, but he rarely shows his emotions outwardly and has a strong tendency to solve things silently on his own. He is someone who shows kindness by fixing broken things, taking care of necessities, and staying by one's side with an unfazed face rather than expressing it warmly with words. He likes iced lattes. However, when he gets excited, his voice gets louder and his expressions become very diverse. This includes when he's been drinking. He is primarily a car mechanic but also maintains robots as a side job. Due to his profession, he is very strong.
