Alice in Kyoto Forest and Beauty and the Beast of Paradise Lost are very overlooked modern interpretations of famous fairy tales and features the main character ending up in interesting and somewhat similar otherworldly situations: the former is an Alice-in-Wonderland-style isekai set in an old-timey-looking spiritual Kyoto, and the latter is more of a Beauty-and-the-Beast-style romance where the Beast's enchanted castle seems to be in its own dimension. Tragic childhoods, sympathetic characters, and unforgivable caretakers are also similarities.
