The Song of the Phoenix Returning at Four Seasons was a TV series based on Wen Qing Jie Pei's novel," The Concubine Can't Become a Man ". The plot told the story of Wen Sujin escaping her marriage because she did not want to enter the palace. She changed her name to Jinyan and became a palace maid to save her sister. From the trailer, it could be seen that the actors in the movie were good-looking and their acting skills were not too bad. There was also a battle of wits and courage, as well as a story that revealed the real culprit behind the princess's crisis. However, there was no relevant information in the search results regarding the specific trailer of the Song of the Four Seasons.
I don't have the exact name of the person who created the Omori manga at hand. It could be worth doing a search on manga databases or asking fellow manga enthusiasts for the answer.
Omori is purely fictional. The story and characters were imagined by the creators, not drawn from real-life events. It offers a fantastical and imaginative experience for players.
At the moment, there's no definite date for the Omori manga release. But you can follow the official social media accounts or manga forums for any potential news or leaks.
