@Anwesha062005 You're welcome! I know how hard exams can be (I've been there, done that, and got the t-shirt for it), and trust me, they are no fun whatsoever, especially when you get stressed out just by having to study so hard for your exams just to get good grades out of your classes. I barely scraped by with a C in my last algebra class in college, and I had to drop out of college a long time ago because the classes were just not the ones I really wanted, which were in-person classes.
And it's alright if you added it in there to avoid losing the story itself. There is actually a way you could add the story in without losing your place on the story itself, and that's by adding it to your private library, then creating a sci-fi reading list later on when you get the chance to do so. I don't think you'd easily lose your place in the story itself, so whenever you get a chance to read it, you can always return to your reading place in the book itself and see where it goes from there.
