Together

Liu Cheng and his thirteen-year-old violin prodigy son Xiaochun travel to Beijing to participate in a competition organized by the Children's Palace. Xiaochun finishes fifth, but the organizers refuse to admit him because he does not have Beijing residency. Disappointed, Liu Cheng resolves to find a private teacher who can nurture Xiaochun's talent away from the public spotlight.

Liu Cheng convinces Professor Jiang, a stubborn and eccentric teacher from the Children's Palace, to take Xiaochun on as a private student. Jiang agrees to mentor Xiaochun, bypassing the residency barrier and giving him personalized instruction. This marks a shift from the competition route to a private, focused training path.

Xiaochun becomes friends with Lili, a young woman living upstairs who supports herself through relationships with wealthy men. Through Lili, Xiaochun enters a different social world and experiences a complicated romance. This growing bond will influence Xiaochun's decisions in the days ahead.

To impress Lili, Xiaochun sells his violin to a shop and buys a fur coat that catches her eye. He leaves the coat at Lili's apartment for her to discover, hoping to win her affection. Hui, Lili's smooth-talking boyfriend, finds the coat and passes it to Lili, claiming it was a gift from him.

Lili confronts Hui about his infidelity in Xiaochun's presence, causing strain between them. She remains unaware for a while that Hui lied about the coat's origin, which deepens the emotional stakes. Xiaochun watches the disclosures unfold with a mix of confusion and concern.

Hearing of Yu Shifeng, a renowned professor from the Central Conservatory of Music, Liu Cheng believes Yu could catapult Xiaochun to fame. He decides to switch Xiaochun's teachers and seeks Yu's mentorship. He visits Yu, sharing the truth about Xiaochun's birth to gain his trust.

Liu Cheng arrives with Xiaochun to Yu's home only to find the violin case empty, signaling a crisis of trust. Xiaochun, furious that his father chose commercial success over art, refuses to play even when offered another violin. In anger, Liu Cheng tears up Xiaochun's previous award certificates.

Lili, remorseful about the fur coat incident, seeks out Professor Yu and persuades him to give Xiaochun a second chance. Xiaochun performs for Yu, and the professor is impressed enough to accept him anew. The rekindled mentorship marks a turning point for Xiaochun's prospects.

Professor Yu also has another talented student, Lin Yu, who is jealous and ambitious. As the international competition's selection trial approaches, Lin Yu and Xiaochun compete for the sole spot. The rivalry intensifies the pressure on Xiaochun to balance emotion, technique, and loyalty.

With the trial looming, Liu Cheng decides to pack up and return home to allow Xiaochun to concentrate and to raise money should Xiaochun be selected. The decision underscores his devotion to Xiaochun and willingness to sacrifice stability for opportunity.

Before the selection, Yu Shifeng reveals the truth about Xiaochun's birth to deepen his passion for music and respect for his adoptive father. The revelation strengthens Xiaochun's resolve to remain loyal to his father and to the music they share rather than chasing fame.

Lin Yu reveals to Xiaochun that Professor Yu had secretly bought Xiaochun's original violin from a shop to prevent distractions. Faced with this information, Xiaochun relinquishes his seat to Lin Yu and chases after his father with the violin. The moment underscores Xiaochun's decision to prioritize family over a single competition.

Xiaochun runs after his father at the train station, choosing family over fame. They are finally reunited, and they decide that being together is more important than pursuing success.
