2+ years ago i read it on nhentai
about a newly moved in family, but im not sure of its members except for the mother and daughter and 1 guy
the guy notices 2 ugly bastards snooping around their apartment then later on the day there is a recording of the mother and the 2 ub
and then at the end of it, revealed a recording of the daughter that is getting passed around the guys living in the building
add. info would be it was b/w with the last panel about a file name on a phone with the daughters name
