The story to be opened can be almost the same as the project story, but it is better to organize it interestingly by focusing on the core content.
The purpose of the story to be opened is to attract interest in the project and induce notification subscriptions, so it is good to add content such as free trials or support signature events along with the attractive parts of the project.
It is better not to include specific delivery information such as the reward delivery schedule, which is subject to change, in the story to be opened. You can describe the sending information in detail in the project story.
Please emphasize elements that can arouse interest, but be careful not to exaggerate the content too much.
