For all of you, who still cling on this VN, I have a bad news for you. This project has been canceled. You can't find the information of this project any where because it just available only in Vietnam (mainly). It's used to have a group for this VN on Facebook and Twitter, but it has been taken down. The cause for this problem seem to be the drama between the main artist, who draws one of the character in this VN ( The white bear), and the group of this project. I don't want to go further for the drama so I don't know what happen at the end, but the outcome for this is that the story has been delayed very long. After the drama and delay, they also lack of fund and skill to maintain the project. So that is the whole thing I know so far. If you want to know more I will give you all the pages that still available at the meantime. Hope you all satisfies with this information.

I have lost theirs main Facebook ( personal) so sorry I can't give you more than I know.
P/s: They used to have a separated version for this VN, but I guess that special version also burn down with the main project.
