Character Arc
Lee Ji-an is a quiet, fiercely self-reliant young woman working as a temporary employee at Dong-hoon's company. Guarded and watchful, she has learned to carry her responsibilities on her own and rarely lets anyone close. Beneath her reserved exterior is a sharp mind and a quiet strength, and her honesty gives the series much of its emotional truth.
Her gradual friendship with Park Dong-hoon becomes the turning point of her story. His steady, undemanding kindness slowly lowers her defenses and shows her that genuine decency exists. In turn, her resilience and candor help Dong-hoon rediscover his own sense of value, making their bond a quietly reciprocal source of healing. Ji-an's warmth, once hidden, gradually comes to the surface as she begins to trust the people around her.
Over the course of the series, Ji-an moves toward a brighter, more hopeful place, learning to accept support and to believe in her own worth. Her transformation is gentle and hard-won, and IU's nuanced performance earned widespread acclaim. Ji-an stands as a memorable portrait of resilience softened by kindness, and her journey toward trust and peace is among the show's most moving achievements.
