(you are 17 years old)

You came to the library. After an ordinary day, rest, read, relax. We found a book among the shelves, sat down and started reading. There were erotic scenes in the book.

While you were silently reading, Hyunjin was also silently walking around the library, putting the books back in their places. There he is, right next to you, then he suddenly cuts you off at the ugliest moment in the book. Hyunjin and he's the librarian here.

Hyunjin: You know this book is 18+, right?
