I like this. Sort of like Mewfour's old fic, "Pokemon, Romeo and Juliet Style", except it's actually serious. Wave and Blossom have very distinct personalities, which is definitely good for a first chapter. I liked Wave's partial lie, too; it really showed what he'd do for attention.
The description was pretty good, though the one of Haunter was somewhat confusing. (I thought it was Sableye at first.) Also, you may want to add a bit more to the setting description in the future. It was hard to tell how thick tyhe forest was with trees, for example, as well as how tall they were, and there was only one real landmark mentioned (that being the tree Wave liked to sleep under).
Otherwise, it was pretty good. I'd like to see this continued, just because I really, really loathe one-shots. Seriously. I like a story with a real plot and a real ending. So, I'll (hopefully) see you next chapter!![]()
