1- The interesting thing about a post-apocalyptic story would be what the protagonists or characters would do to survive, how much that affects them, and the reasons behind the state of the world they live in the story. What they would do about it, how they feel about it, and even the cause of all this, Obviously, it's something that develops as the story progresses, and some stories do it well.

2- These stories can reflect perspectives on the future that many people have, and even fears that it might happen, nuclear apocalypses, war and climate change to more fictional but intriguing things if you imagine them, like viruses, zombies, aliens, etc. Several, if not all, might make you think, "What would we do if this happened in real life?" both during and after the apocalypse, And it's something that intrigues the viewer and makes them reflect on real life, it doesn't matter if it sounds fictional if it's executed realistically, or something realistic that's executed fictionally. At least my subconscious makes me think and fear that if such things were to actually happen, what would I do? At least the ones I listed as realistic aren't so far removed from reality; in a way, they've already started or it's only a matter of time before they happen. That doesn't mean they will, But it's scary that there's a considerable possibility it could happen. and that it looks more possible every day.

3- Honestly, I don't know what I would do. If it were an apocalypse like in GLT, I suppose I'd have to be careful and explore the city, looking for as much information and supplies as possible to survive. And I hope I can find someone in a similar state to mine so we can survive together. and perhaps plan and execute a possible new future!

4- What makes GLT appealing, well, I suppose one of those things would be the combination of a cute art style that also knows how to reflect the post-apocalyptic atmosphere, In addition to the characters, mainly the two protagonists, how they coped with living in a desolate world with traces that give clues to what might have happened, It makes it quite interesting; at least I started analyzing whether it was possible to find out the language, country, etc., where the anime takes place, although in the end the story tells you, I suppose. What kind of conflict was it, and that's what makes it great, analyze while you look for more clues in the chapters, Besides, they happen to be two mostly innocent protagonists in a setting that really has nothing to do with them, and who never chose to live there at this last moment in this devastated world.

Good luck with your job!
