If you watched RiaBB because you love books you will enjoy CT. While one is a romantic comedy and the other is a drama they both share the love of books and reading as well as beautiful quotes.

Both dramas have a special quality to them. Heavy emotions and lots of thought provoking scenes but without being too heavy to watch.
They also have a little bit of similarity in the bromance - especially the dramatics of the ghostwriter compared to the goblin...
Story wise there’s not many similarities except for the reincarnation aspect, and the love story is quite different. (Also, the relationships might be a bit off but there’s a lot of possibilities for SLS in Chicago Typewriter, or third or fourth...)
