Gu Chaoyan was extremely smart, but she was slow about some things. For example, when it came to someone else liking her. She would not understand romance unless Zhou Huaijin told her about it personally. She was not aware of how differently she was treated by someone who adored her.

However, when it came to the book, everything seemed so clear and straightforward, so even Gu Chaoyan realized that something wasn't right.

If he just forgot to return the book, then it was probably because he did not pay much attention, but Duke North was holding the unimportant book to his chest even when he was deeply injured, it basically meant that the book was of great importance to him.

Gu Chaoyan was engaged, and Duke North was engaged too.

So the whole thing started to become very embarrassing.
