When the owner of a flower shop and the proprietor of a liquor store marry, their respective sons, Chiaki and Mine, suddenly find themselves living together as stepbrothers. This unexpected union merges two very different worlds into one household, forcing the young men to navigate a complex new family dynamic while adjusting to each other's contrasting personalities and daily routines. Despite growing up surrounded by his family's alcohol business, Mine harbors a rather ironic secret: he has an incredibly low tolerance for liquor and becomes intoxicated with startling ease. This vulnerability quickly catches Chiaki's attention, setting the stage for a series of unpredictable encounters. As Mine frequently stumbles into drunken mishaps, Chiaki begins to explore just how far he can take advantage of his new stepbrother's uninhibited state, leading to a tense and playful exploration of their shifting boundaries. The unfolding relationship between the two stepbrothers drives the core narrative, blending everyday domestic life with moments of heightened romantic tension. Their evolving connection is further enriched by the inclusion of two additional side stories from Rule Sono Ichi, offering readers deeper insight into the characters and the unique world they inhabit.
