It's hard to say for sure. You'd need to look at the source and any background information provided. If it's presented as a memoir or based on documented events, it might be true. But if it's clearly labeled as fiction or fantasy, then it's likely made up.
We can get the answer: the reason why it took two and a half hours to get back was because there was a traffic jam on the way back or maybe it was because of the delay on the way home.
It depends on the specific platform or app you're using. Some might let you view it after 24 hours, while others might not. You'd have to check the settings and policies of the particular service.
I'm not entirely sure specifically as there could be many 'golden hour visual novels'. Generally, a visual novel often involves a story with characters, plotlines, and usually has some sort of decision - making elements for the player. It might be set during the 'golden hour' which could imply a time of day like sunset or sunrise that gives a special aesthetic to the story.
I'm not sure specifically what this 'golden hour graphic novel' is about as there could be many with that name. It might be about a special time period (the 'golden hour' which is often used in photography to refer to the hour after sunrise or before sunset) and some kind of story told in a graphic novel format. Maybe it involves characters whose lives are somehow related to this time of day, like a mystery that unfolds during the golden hour.
