The 24-year-old Pei Sheng fell into the Wei and Jin Dynasties more than a thousand years ago, and when she woke up, she found that she was blind. She came here for no reason, and she didn't know if she would return. She thought she was happy with the situation and told herself to adapt to the ancient life, dealing with her predecessor and the problems she created. Many years later, she slowly adapted to the life here, saw the world again, happened to meet the Lanting Gathering in Kuaiji, and found someone who liked herself. Everything seems to have a perfect ending, but only she knows how clearly she realizes that her loneliness is incompatible with this era every time night falls and drinks alone under the moon, and how much she misses her parents, family, and friends in her heart. The painful struggle every day, when she is on the verge of collapse, suddenly finds the hope of returning home. For her, leaving or staying has become an extremely difficult multiple-choice question.
