Add Bookshelves to Each Other. Reach Each Other's Roots.

I want to read a book similar to "Online Games: Reshaping Life". My purpose is very clear, which is to add books to each other's bookshelves and follow each other's roots. Of course, if you need a one-hour book review or the like, you can make another appointment and leave a message under my recommended book. I won't be able to stay overnight that day.
