On a snowy train ride toward Tokyo, two twenty-year-old women cross paths. Both share the name Nana, yet their temperaments and origins could hardly be more disparate. Nana Komatsu is naive, romantic, and eager to build a life centered on relationships, having left her hometown to follow a college boyfriend. Nana Osaki is sharp-edged, fiercely independent, and driven by raw musical ambition, determined to make her punk rock band, the Black Stones (Blast), a force in Japan's commercial record industry.

A chance encounter at Apartment 707 leads them to become roommates, establishing an unexpected domestic sanctuary. While Nana Osaki works to assemble her band and confront the emotional weight of her past with Ren Honjo—now the lead guitarist of the superstar rock group Trapnest—Nana Komatsu stumbles through financial insecurity, workplace disillusionment, and chaotic romances. Their sisterly bond deepens into a lifeline as the realities of the commercial music industry collide with private vulnerabilities.

As Blast catches corporate attention and rivals Trapnest, the personal lives of both bands become entangled. Fame introduces relentless tabloid scrutiny, shifting contracts, and psychological fractures that threaten the stability of Apartment 707, steering both women toward irreversible choices.
