The musical follows Han Soo, a college graduate still searching for full-time work, who moves into a low-rent rooftop unit where three other residents—each with unfinished dreams and stalled careers—live in fragile coexistence. Their daily routines, arguments, and small triumphs unfold as they confront debt, part-time jobs, burnout, and the fear of wasted youth. Rather than offering a dramatic reversal, the story emphasizes emotional survival, chosen family, and the quiet strength of continuing forward in a society obsessed with visible success. The tone is warm, observational, and lightly comic, with songs that mirror everyday speech and inner monologue.
