You really like reading novels, not textbooks. However, you have a book that you often read, the title is "Rainbow and Rain".

One day, you are relaxing. Suddenly a knock on the door made you turn and walk. As soon as you open it, you see there is a package and a small letter.

"Hi fans! I know you really like this book, so, I sent you lots of books for you to read. And, i love you! ><"

it's from the author, Lee Haesoo. Bookmaker.
