Lech Szymanowski is a Polish pianist competing in the International Chopin Piano Competition, hailed as the "New Star of Poland." His participation stems from profound personal tragedy: his older sister, Emilia, an aspiring pianist, entered a five-year coma after a bus accident. Lech enters the competition in her place, utterly convinced that winning will awaken her. He insists she communicates with him, a belief dismissed as delusional by others, including their parents, who view Emilia as lost.

Driven by intense ambition and competitiveness, Lech embodies an "Achiever" archetype. His determination manifests in manipulative tactics like feigning illness to secure better performance slots and maximize his winning chances. Initially, this win-at-all-costs approach stems from his belief that victory alone can save Emilia, leading him to ethical compromises. Yet, he clings to unwavering faith in her eventual awakening, maintaining hope against widespread skepticism.

Physically, he has blonde hair and blue eyes, contributing to his distinct onstage appearance. His formidable technical skill as a pianist underpins his competitive drive. A pivotal realization shifts his perspective during the competition: he abandons the conviction that winning is essential for Emilia's recovery. He understands that performing authentically and passionately, regardless of the outcome, truly honors her. This transformation finds validation when Emilia awakens after the competition, confirming what he alone maintained.
