Pang Wei is a wealthy Chinese pianist studying in Poland. Childhood bullying led him to withdraw socially, embracing music as his sole companion. This isolation forged both a distinctive piano style and a dismissive attitude towards others, whom he typically perceived as unworthy competitors.

His piano technique bears a striking resemblance to Sosuke Ajino's style before Ajino's career-ending accident, a similarity noted during the International Chopin Piano Competition where Pang Wei is a top contender.

Raised harshly by a guardian focused solely on molding him into a renowned pianist without genuine care, Pang Wei developed an intense drive for validation and success. His competitive mindset crystallized in the declaration, "I'm going to win. No matter what it takes." His technically masterful performances initially carried underlying anger and sorrow, evoking unease even in joyful pieces.

A pivotal confrontation with his past trauma, triggered by a kidnapping and a consequential conversation with Ajino, sparks a significant emotional shift. In his final competition performance, Pang Wei channels profound happiness instead of anguish. This cathartic experience leads him to openly weep while playing, marking his decision to leave behind the long-held resentment shaping his music and interactions.

His relationships remain complex; he actively avoids friendships and reacts angrily to accusations of plagiarizing Ajino. Despite this defensive, antisocial demeanor, he demonstrates capacity for change by offering sincere congratulations to Kai Ichinose after Kai's victory, signaling a softening of his rigid outlook.
