i love the manga! it reminded me of the manga Witch Hat Atelier which is also really good!
For Theo to have the love of books and cry during one of the books he read made me cry as well. Not specifically this scene that made me cry but the amazing artworks that you did as well as the tiniest details that you drew, made me draw into the manga and made me amazed with the art style. Mostly the amount of books you carefully drew made me want to pursue my dreams, to read all the books that i come across!
I hope you the author will continue to create the continuation of this manga because by far, this is one of my favourites!
