The last two updates have only dealt with specials, once Halloween and once Christmas.
Personally, I don't mind stories that are a bit off the MC's radar, however, I think such stories should contribute something to the main storyline. I don't know how much is planned for this VN, but for example something about the story of MC's father and how Nova ended up where she is now, or maybe, if it's technically possible, something about the childhood of MC and his peers. Just something with added value. And not necessarily two in a row.
