Kuroko begins a ritual she calls brand patrol, or Brapat, repeatedly visiting stores to acquire her dream designer handbag, a Fourkin. She shares her Brapat experiences on social media, where she finds herself confronted by an account that persistently harasses her. The person behind the online attacks turns out to be a work colleague she greatly respects. This discovery forces Kuroko to navigate a complicated conflict between her professional admiration for a mentor and the personal hurt caused by their online behavior.

Through her Brapat activities, Kuroko's world expands as she meets a variety of people. Her social circle and experiences grow to include her boyfriend who becomes obsessed with a watch marathon, a dedicated brand customer who has a personal sales associate, and a formidable online patrol enthusiast. These interactions deepen her engagement with brand culture and the communities that form around luxury goods.

In the concluding narrative arc, Kuroko is invited to the home of a fashion magazine editor-in-chief she befriended through their shared interest in the brand called Bright. The editor proposes that Kuroko participate in a competition for a major fashion event called TOR, the Tokyo Orange Runway. This competition introduces a quiet rival and takes Kuroko to Hawaii for a Brapat adventure. The story concludes as Kuroko pursues her professional ambitions and personal dreams, ultimately seeking to finally obtain her cherished Fourkin bag.
