Kazuya's friend Shirou has a tendency to ask girls out without a lot of planning or concern about the outcome. Just when it seems like that approach has finally managed to endear himself to a girl, the looming threat of an amasogi puts a damper on any potential romance.
Breaking that taboo by enjoying 
them in secret is half of the fun.
.مخالفة تلك المحظورات عن طريق الاستمتاع بها سرًّا هو نصف المتعة
Die zu verstecken ist
schon der halbe Spaß.
Disfrutarlas en secreto
es mitad de la diversión.
Disfrutarlas en secreto
es parte de la diversión.
Ah, le plaisir pervers
de les consulter en cachette.
Metà del divertimento sta proprio
nell'infrangere quel tabù e leggerseli in segreto.
Quebrar o tabu de apreciar esses
livros em segredo é parte da graça.
Вся прелесть именно
в развратности чтения тайком.
