Between the Pages

Bruno had resigned himself to the fact that the entire Encanto hated him until he met the seemingly quiet librarian's daughter. In hopes of a new friend, he found a loud, adventurous, and imaginative young girl who didn't care what others thought of her. She was Julieta's friend first, but soon the two of them become inseparable, and Bruno's feelings for her, no matter how hard he tried to suppress them, keep growing.

Emilia had tried to avoid marriage as much as she could. Her brother and sister-in-law had tried to set her up with countless men, but Emilia scared them away, insisting she just wanted to exist and be her own person in the world. Then she meets Bruno and believes she found her person, a platonic partner through life until those feelings begin to turn romantic.

Takes place 14 years prior to the events of the movie, so it's about 1936. The triplets are 36 and Emilia is 21. Luisa just turned 5.
