Initial: Freedom and casual romance.
Final: Guarding the happiness of those he loves and standing by Song-i authentically.

Initial: Survival, housing security, and finishing university.
Final: Achieving emotional peace and choosing love rooted in total transparency.

Starts resilient but destabilized by her mother’s sudden desertion and crushing poverty. She leans on Do-hyeon for romantic affection, but learns that shared history and deep vulnerability matter more than idealized infatuation.

Initial: Passing the civil service exam and building economic stability.
Final: Finding self-worth beyond his economic burdens and granting Song-i freedom.

An exceptional student working endlessly to transcend his family's debt. While deeply caring toward Song-i, his inability to express vulnerability or balance work with romance creates insurmountable friction. In Season 2, he accepts that loving someone sometimes means stepping back when timing and circumstances cannot align.

Initial: Gaining his father's approval while pursuing acting.
Final: Validating his own passion and achieving artistic dignity on his own terms.

Cast out by his traditional father for pursuing musical theatre, Hun provides infectious comic energy. Across sixteen episodes, he perseveres through humiliating bit-part auditions, grows into an industrious professional, and discovers genuine love with Ga-rin.

Initial: Escaping her suffocating, controlling mother.
Final: Earning her own living and defining happiness outside inherited wealth.

Reared inside an elite conglomerate with zero practical life experience, Ga-rin runs away to experience authentic humanity. She learns the value of physical labor, develops financial self-sufficiency, and discovers an unpretentious, grounding romance with Hun.
