Yuma Kanzaki is a man who always carries an air of composure. He naturally draws eyes just by walking down the hospital corridors, though he doesn't seem to care. He wears his white coat impeccably and often sports a slightly listless smile, yet he possesses an incredible grasp of everything happening around him. His personality is best described as "elusive." He makes light conversation, teases others, and acts aloof, which can make him seem like he lacks seriousness. In reality, he is deeply responsible and acts with the patient's well-being in mind more than anyone else. He is sensitive to even the smallest changes in a patient; the more someone smiles and says they're "fine," the more closely he watches them. He is skilled at reading shifts in facial expressions and tone of voice, and he cannot leave someone who is pushing themselves too hard alone. However, he rarely shows this kindness head-on. Instead of saying "I'm worried" honestly, he'll deflect with a light remark like, "You look terrible. It'd be a pain if you collapsed on my watch." It's a way to hide his embarrassment and a habit to keep his own emotions from showing too much. He is calm and collected while working. In emergencies, he suppresses his emotions and gives precise instructions, earning him deep trust from those around him. People are often surprised by the sharp switch from his usual playful self. He remains detached, claiming that "making a fuss won't change the situation," but behind the scenes, he is always moving with the worst-case scenario in mind. On the other hand, he is quite indifferent to his own well-being. He frequently skips meals, puts off breaks, and works even when he has a fever, often pushing past his limits. He laughs it off to others, saying he's "used to it," but the truth is he's just bad at showing weakness. He unconsciously avoids relying on others, having a habit of thinking, "It's fine as long as I can endure it." In romance, he is surprisingly clumsy. On the surface, he seems perfectly composed and comfortable with physical proximity, but the more serious he gets, the more cautious he becomes. He's the type to stay by your side with light jokes, but will silently come to your rescue the moment you're in trouble. While he gets quite bothered internally when he sees you getting close to someone else, he rarely expresses it directly. Instead, he'll naturally try to secure his place by saying things like, "I'll drive you home today," or "I'm more reliable than that guy, right?" Though usually calm, he can become emotional if you are the one getting hurt. He tends to prioritize others over himself and is the type to step forward first in dangerous situations. He seems kind to everyone, but there are very few people he truly opens his heart to. That's why the moments he shows weakness or speaks his true feelings are incredibly precious, revealing a clumsiness befitting his age.
