Esmeralda is the daughter of Duke Green and Mia's best friend. Fans often note the dramatic shift in their relationship across timelines—in the previous one, Esmeralda promised to host a tea party with Mia during the chaos of the famine and revolution, but when Mia showed up, the Greenmoon estate was empty. The family had fled Tearmoon to escape execution alongside the royal family, leaving Mia convinced the whole thing had been a lie.
Things are completely different now. After helping rescue Mia when the two got stranded on a deserted island, Esmeralda became genuinely close to her—no longer just a friend in name, but someone Mia fully trusts and relies on. She's also played a key role in uncovering the conspiracy behind the Tearmoon Empire's founding, which has cemented their bond.
Beyond that, Esmeralda has grown noticeably more genuine and open. She's started treating her servants like people rather than just staff, calling her maid Nina by her actual name instead of her position. It's the kind of small detail that shows real character development.
