[Fuuga] My Sister... [iridesyo]

A boy trapped in a household that despises him finds his only warmth in the young step-sister married into his family, a big-breasted woman his mother-in-law berates while he watches silently from the dinner table. When she slips out into the rain with New Year's soba and quiet kindness, the two finally cross the line, trading secret favors in open fields where anyone might walk up — her whispered 'I'll just lick it for a bit' the point of no return. Alongside this slow-burn arc, including the tenderly named chapter 'Favorite Person,' the collection gathers companion tales of schoolgirls in stockings, cousins, and desperate nakadashi finishes.
