Carter pretended to be poor and approached her merely as a shield for his adopted sister Sienna. Sienna steals Stella’s identity and affection, setting traps against her repeatedly. Carter’s bias leaves Stella injured and humiliated. Heartbroken, she transfers school to chase her dream, supported by loyal friend Felix and producer Rowan. When Carter realizes Stella is the singer who healed his depression, he obsessively tries to win her back. Stella clears her name, earns her admission to Berklee, rejects Carter firmly, and embarks on her bright musical future.
