Y/N enters a sugar arrangement to solve her financial struggles, expecting a simple, strictly transactional deal. Her client, Satoru Gojo, is an older wealthy man who initially treats it casually—but over time, their dynamic shifts into something more intense and emotionally complicated, as he begins to develop a growing fixation on her. In parallel, Y/N’s best friend Lina starts her own arrangement with Suguru Geto, forming a calmer, more controlled dynamic that contrasts with Y/N and Gojo’s escalating tension. Shoko Ieiri remains outside both arrangements, observing everything from a grounded, realistic point of view. The story explores two contrasting relationships: one slow-burn and stable, the other increasingly obsessive and emotionally charged.
