This is, to some extent, following the logic of the manga, except they fuck in not any notable circumstances, where in the manga, theoretically, they would fuck during a notable event like their graduation(HS or Collage) or their wedding day, that's the only thing that doesn't follow the logic of the manga, if u ever read the manga u will get what i mean. Good Doujin, even thou it doesn't reflect the drawing style, it reflects the personalities and logic of the manga. Thank You.
