Blue Box #1 by Kouji Miura

Volume one has a guy thinking about living with a girl, and there’s a frame of a girl in a bathtub, but you can’t see anything. It is not overtly sexual and does not cross the line for middle school. See the image here.
RFS Rating: Middle School and Up
Blue Box #2 by Kouji Miura

Volume two has a girl changing behind a door and a boy on the other side thinking about it in an embarrassed and flustered way. He ends up saying that the girl doesn’t think of him as a guy. While she’s changing, you can see her stomach and legs. It does not cross the line; see the image here.
