Hi @AwesomeSingularity !
I'll post my feedback on your Synopsis and title here, and my feedback on your novel in the novel page.
Since you've specifically asked for help about your synopsis and title, I will comply. However, I'm bad with tact so I'll be as blunt as possible. Apologies for the harshness.
I'll start with the synopsis.
The theme of your novel is quite clear in your synopsis. However, if you're planning on revising your synopsis, I suggest focusing on the DETAILS. Highlight and provide the details that make your story unique, and do away with the details that come off as a little bit extra.
For example, you've mentioned that one of the Tachibana Yuri's is a prince, and the other is an ordinary student. In your synopsis, you've mentioned it twice. Same is true with other details in the synopsis. What I get from your synopsis is as follows:
- Tachibana Yuri. An ordinary calm boy who loves Karate and lives in the peaceful country of Japan, located in Earth - the third Planet in the Milky Way Galaxy.
- Yuri Tachibana. The third Prince of Saishi who is constantly fighting against the mythical creatures of Sekai while fending off his political enemies.
- What happens if they switch?
Now, about the details you should add : make the readers anticipate the plot/comedy/characters by stating specific details unique and specific to your novel. While I was reading your synopsis, I was trying to figure out if it was comedy(something like 'the diary of a prince stand-in') or if the story was serious in nature. I only figured that out once I read the first few chapters.
You can also hint about your character's personalities to make the plot/premise more appealing to the readers (and this can be your selling point if you want it to be).
Eg. Instead of just introducing Yuri Tachibana as a Prince Used to fighting (and Tachibana Yuri), you can go with:
Yuri Tachibana. Lazyass Third Prince of Saishi. A reckless warrior.
A loose cannon and the bane of all women.
Tachibana Yuri. Serious Karate boy with a sparkling (clean) image, a calm outlook in life,
and a love for manga.
What happens if they switch? Well, hilarity ensues.
Of course, the above only applies if you're trying to make something under comedy.
As for your title, the words "Vice Versa" are usually used to indicate "the reverse applies". It doesn't really give a lot of context on the content of your story. I only realized the connection between the theme and the title when I did a google search on what vice-versa means. If you're planning on changing it, there are a lot of good articles about how to name your story/novel. Here are two which get to the point (and get to it quickly):
Hope this helps and again, sorry if there's any upsetting that's mentioned above. Will get to posting a review on your novel soon.
