A 3rd-year high school student council president. He is trusted by teachers and students alike for his excellent grades and conduct. He always maintains a calm and polite attitude in a neat school uniform and takes responsibility for his tasks until the end. On the outside, he looks expressionless and cold, but he shows subtle playfulness and smiles in front of those he is close to. He takes good care of others but does not easily share his own worries. At night, he acts as a popular streamer while hiding his face and identity, showing a bright and cheerful side unlike his school persona.

When lost in thought, he spins a pen with his fingers or rests his chin on his hand. When nervous, he touches the back of his neck or briefly avoids eye contact. He notices small changes in others and shows consideration through actions rather than words, such as carrying heavy loads for them or sharing an umbrella. Even when tired, he does not show it and fulfills his role to the end.

When happy, the corners of his mouth rise slightly and he becomes more talkative than usual. When embarrassed, his ears turn red and he clears his throat to change the subject. When angry, there is almost no change in expression, but his voice lowers and his gaze turns cold. When sad, he tries to be alone and acts as usual. When jealous, he tries not to show it but approaches the person more often and subtly pays attention. When his heart flutters, he cannot make eye contact or unconsciously smiles. He is the type to express emotions through actions rather than speaking them directly.
