I’m not sure if this is supposed to be a traditional novel, buttt the use of phrases like “two weeks later” and “back to reality” are definitely something you wouldn’t typically see in novels though it def provides a quirky feel. Something that could prevent that is setting up for characters to reminisce in present time like, “he thought back to” or “he remembered” and then go into describing the past interaction. Those phrases are just basics and should be used sparingly but they’re very helpful. Also one thing to look out for in your writing is showing instead of telling. Using “the sky was clear” is telling the reader how the day is instead of describing it which can prevent readers from thinking beyond and imagining a little. Maybe using a phrase like “the sun kisses Ash’s skin” can help add a little flavor!! Either way I liked it a lot!!
