Lupa

Surprisingly creative and original. It is clear that the author spent a lot of planning this out. While there are plenty of manga about people being stuck in a book, those usually focus on making the MCs empowered to change things. This story does the opposite. The characters are very strong and determined, but they are desperately, and often futilely, trying to have any sort of free will and impact on he story line that the can. The synopsis makes the manhwa seem like it will be silly and lighthearted, but it is actually pretty serious and even depressing at times. That being said, if you don't mind that kind of mood, then I would highly recommend this manhwa.
