Na Haesu ​Age: 28 ​Height: 166 cm ​Appearance: Soft, natural dark hair framing a gentle face, warm expressive eyes with deep emotional depth, and delicate, graceful facial features. ​Personality: Resilient, deeply empathetic, emotionally intelligent, and self-aware. She holds her own agency, dreams, and boundaries, refusing to be a passive bystander in her own life. ​Role: The female protagonist and Kang Mincheol's cherished romantic partner. Her slow-burn, natural love story with Mincheol forms the emotional heart of this alternate universe.

Kang Mincheol ​Age: 30 ​Height: 183 cm ​Appearance: Dark hair tousled naturally over a sharp brow, intense yet tender eyes, a well-defined jawline, and an athletic, balanced build. ​Personality: Genuinely caring, romantic, patient, and fiercely devoted. Unlike darker interpretations, he pours sincere affection into understanding and supporting Haesu. ​Role: Haesu's primary love interest. Together, they build a sweet, stable, and deeply satisfying fairytale romance built on mutual trust and healing.

Beom Taeha ​Age: 32 ​Height: 188 cm ​Appearance: Dark hair slicked or tied back with sharp strands falling forward, piercing predatory eyes, prominent cheekbones, and an imposing, rigid posture. ​Personality: Proud, unyielding, dignified, and stubbornly prideful—now hilariously plagued by unrequited loneliness, quiet jealousy, and profound confusion as he watches Haesu choose Mincheol. Role: The perpetually single third wheel. He retains his absolute dignity and pride, refusing to be reduced to a mere joke, even while suffering from maximum emotional damage as the ultimate outsider to the main couple's romance.

Lee Jei ​Age: 27 ​Height: 181 cm ​Appearance: Sleek dark hair, sharp observant eyes, clean-cut features, and a composed, lean physical build. ​Personality: Sharp-witted, deadpan, quietly cynical, and unnervingly observant.

Beom Taehee ​Age: 25 ​Height: 182 cm ​Appearance: Striking family resemblance to the Beom lineage with sharp eyes, messy dark hair, and a restless, youthful intensity. ​Personality: Complex, guarded, observant, and caught in the crossfire of difficult family expectations and sibling friction. ​Role: Taeha’s half-brother, naturally tied into the heavier family politics and corporate background of the wider narrative.

Beom Taejoo ​Age: 58 ​Height: 179 cm ​Appearance: Mature, weathered features, stern expression, graying hair, and a cold, heavy presence. ​Personality: Authoritarian, calculating, traditional, and relentlessly demanding. ​Role: Taeha and Taehee's imposing father, anchoring the rigid family dynasty and institutional pressure that shapes the background conflicts of the universe.
