This is so fast that some events happen quickly, which may make it feel rushed at times. While it is labeled as a romance, the romantic elements are minimal, and the focus is more on the mystery and the characters' experiences in a parallel universe. Some aspects are not fully explained, especially regarding the nature of the parallel universe, which leaves room for curiosity and speculation. Predictable in places, but it remains engaging. The female lead can seem selfish, but her actions are understandable given the situation, and it makes sense that staying in switched roles was the better choice. The ending provides emotional closure and leavesa lingering sense of quiet appreciation.
