Luca Couffaine

Lucas Couffaine, as the physics and mathematics teacher, is a handsome young man with dark, wavy hair, slightly carelessly styled, expressive eyes, and a calm half-smile. He wears formal but not overly formal clothes—for example, a shirt with rolled-up sleeves and a vest, as if he wants to appear approachable to his students. His character combines patience and demandingness: he clearly explains complex formulas, takes his time if someone doesn't immediately grasp the concept, but firmly insists on discipline and precision in calculations. At the same time, he knows how to spark interest in science with a few unexpected examples from life and is always ready to stay after class to help solve difficult problems.
