Sariel, also known as Qi Sili, is one of the most lore-rich characters in the otome mobile game. Throughout his route, players gradually discover that beneath his composed, ultra-refined fashion designer persona lies a deeply supernatural history. He is closely tied to concepts of fate, otherworldly forces, and hidden identities that make his route one of the most discussed in the community. Many fans describe his story as the most emotionally complex arc in the game, touching on sacrifice, immortality, and the price of a double life. His true nature is revealed in layers, which is why the Sariel plush and Qi Sili plush resonate so deeply with players who have completed his route and formed a strong attachment to the character.

Osborn occupies a fascinating grey area that makes him one of the standout male leads in the game. On the surface, he presents as rebellious, morally ambiguous, and even intimidating, which is part of his appeal. His work as a bounty hunter for the Longday Guild places him outside the law, yet his core identity as a competitive racing champion and his fierce protectiveness make him unmistakably a love interest. Fans frequently discuss whether Osborn leans antihero or romantic hero, and that tension is a major reason the Osborn plush is so popular among players who gravitate toward complex, layered characters in otome games. His route explores trust, identity, and loyalty in ways that consistently surprise players.

Both Sariel and Osborn have passionate fanbases, though they attract different types of players. Sariel (Qi Sili) tends to attract fans who love mysterious, intellectually sophisticated love interests with hidden depths and an elegant aesthetic. The Sili plush and Qi Sili plush are consistently among the most requested fan items from players who have completed his route. Osborn, on the other hand, is beloved by fans who prefer bold, rebellious characters with a protective streak and an exciting lifestyle. Popularity polls across international fan communities frequently show these two at or near the top of the rankings. Ultimately, the choice often comes down to personal type, which is why both handmade character plushies are popular as fan collectibles and gifts.

Qi Sili is the romanized form of the character's name as it appears in the original Chinese release of the game. The name carries a melodic, refined quality that suits his elegant, high-fashion persona as an internationally acclaimed designer. When the game was localized for international audiences, the name was adapted to Sariel, which carries a similarly ethereal quality, fitting for a character tied to supernatural and otherworldly themes. International fans who discovered the game through the Chinese version often use both names interchangeably, which is why searches for both the Sariel plush and the Qi Sili plush appear frequently in the collector and fan art community.

The Longday Guild is a secretive organization within the game's world that operates outside conventional society, taking on high-risk contracts and assignments that involve tracking, retrieval, and other covert work. Osborn's dual identity as a celebrated racing champion and a guild bounty hunter is central to the tension in his route, as the protagonist must navigate the danger and unpredictability that comes with loving someone embedded in that world. The guild serves as a major story vehicle for Osborn's route, raising questions about loyalty, freedom, and what it means to truly trust someone with a double life. Fans of the Osborn plush often cite this storyline as one of the most thrilling in the game, blending action-adventure elements with the emotional beats typical of a well-crafted otome route.
