Netsuzou Trap -NTR-

High schoolers Yuma Okazaki and Hotaru Mizushina have been inseparable since childhood, and their days feel comfortably settled alongside their boyfriends, Takeda and Fujiwara. Between ordinary school life and casual group outings, their friendship seems like the one constant nothing can shake.

That certainty falters during a group date when Hotaru crosses an unexpected line, touching Yuma while the boys aren’t paying attention. Startled, Yuma slips away to the restroom, only for Hotaru to follow her into a locked stall and murmur that she’ll “help” Yuma practice for being with a boy—turning a familiar bond into something tense and unsettling.
