I'm not sure exactly when the closed beta for Maple Story 2 will end. You might want to check the official game website or social media channels for the most accurate and up-to-date information.
Well, 'beta test end novel' might imply that a novel which was in a beta test, perhaps an e - book or a new release in digital format, has reached the conclusion of its testing period. This could be a sign that the author and publishers are now ready to make final adjustments based on the beta test feedback and move towards a full release.
It could mean that in the context of the 'alpha novel', the beta (which might be a version, a character, or an idea) has rejected something. For example, if the alpha novel is about a creative project, the beta version of the project might reject certain elements proposed by the main or 'alpha' concept of the novel. It really depends on how these terms are defined within the specific world or narrative of the novel.
The ending of the anime console had yet to be decided because there was no official announcement of the ending. However, according to the development of the plot and the feedback from the readers, the anime console would likely have a happy ending.
As for whether the anime console would have a second season, there was no official information on whether it would have a second season. If there is any relevant information, I will update it as soon as possible.
