Sure, 'Do It Once More' manga has gained a significant fan base. The engaging plot and well-developed characters attract a lot of readers. Also, the unique themes explored in it contribute to its popularity.
I'm not entirely sure as it could be a very specific or indie visual novel. It might be about a story that's being retold 'once more', perhaps a redo of a classic story in a visual novel format.
Usually, a novel could only be submitted to one journal or publishing house and could not be submitted to multiple journals or publishing houses at the same time. This was because every journal or publishing house had their own submission standards and requirements, and the submission process also had to follow a certain submission process and time limit.
If a novel met the submission requirements of a certain journal or publishing house and had already submitted a submission application, it could not be submitted to another journal or publishing house. Otherwise, it would be regarded as a duplicate submission, which might have an adverse effect on the author's right to submit.
Therefore, if you want to submit a novel to multiple journals or publishing houses, you should first understand the submission requirements and process of each journal or publishing house and ensure that your work meets the submission standards of all journals or publishing houses. Then, he would submit the manuscript according to the submission process of each journal or publishing house to avoid unnecessary misunderstandings and trouble.
Well, it varies. If you have a lot of free time and can read quickly, maybe three or four. But for most people, one or two at a time is doable without getting overwhelmed.
