Description
Hye In is a 15-year-old South Korean student enrolled in the Prism Study Abroad Program at Japan's Pretty Top Dance School. She has long auburn-brown hair, sharp light blue eyes, and consistently wears a distinctive yellow hair clip. Standing 162 cm tall, she favors dark-colored outfits, particularly styles from the Dear Crown brand.

Her personality blends lively energy with intense seriousness toward her Prism Star career. She follows a grueling training regimen—running 30 laps, completing 200 push-ups, or practicing beach flag exercises—cultivated during her early endurance-focused discipline at Korea’s Dear Princess academy. Though confident in training, she harbors self-doubt over her lack of a unique specialty, leaving her vulnerable to manipulation when results falter.

Hye In shares a deep bond with childhood friend Mia Ageha, whom she met in Korean elementary school. Their pact to debut as Prism Stars fuels a friendly rivalry, reinforced by flashbacks of their promise and ongoing video calls where Hye In supports Mia’s ambitions.

At Pretty Top, Hye In questions Prizmmy☆’s debut without a Prism Act, contrasting their relaxed approach with PURETTY’s rigorous schedule of waking, training, and eating. After losing a ping-pong match to Prizmmy☆, Rizumu helps her recognize PURETTY’s weakness: disjointed teamwork. Hye In refocuses efforts on unity, enabling PURETTY’s debut.

As PURETTY’s de facto leader, Hye In guides the group diligently. She engages with Symphonia Series tournaments, sponsors Dear Crown designer Yunsu, and wins the MVP award and Symphonia Dress at the Symphonia Summer Festival despite not winning the event. Later, frustration surfaces when Mia’s Symphonia dress evolves mid-performance while hers remains unchanged, intensifying her insecurities.

Her growth involves balancing relentless drive with self-trust. At the Grateful Symphonia tournament, she ties with Mia for the center position. Their joint performance crowns both as centers, resolving Hye In’s doubts and affirming her value beyond hard work.

Her coord outfits include the Dear Crown PURETTY Rouge Jacket set for Prism Shows, Rhinestone Bare Top for Symphonia festivals, and Dancer Dreadlocks Hair for P&P activities. Her Prism Jumps feature "Golden Spiral" (later upgraded to "Platinum Spiral") and "Golden Star Illusion."
