Regarding the title: The original title is Toriko to Narite トリコトナリテ. The kanji are probably 虜となりて meaning something like “I will be your captive” or “the willing captive”, with a subtext of “captive/prisoner of love”, i.e., madly in love. I am the translator, and I chose to go with "Enthralled" because it is the catchiest thing I could come up with that is faithful to the original.
The author posted a fragment of the manga (raw Japanese) on her Twitter with the headline “The Story of the Wolf Husband and the Rabbit Wife”:
