Common human behavior, killing anything and everything that are different from them.
That girl was probably the one that was shot by the guy, dude definitely wants to take her home, which i dont know if the winged girl would agree (She probably would though, the art style suggests it, this kind of manga usually dont have much plot twists and just go along with the readers need-romance)
The witch girl is probably another one of those cold heart that will get melt by a hot headed boy or a blond knight
The background characters are the same old loud, mob villagers hive mind that will definitely burn the witch girl if she disobey their order (Which she definitely will), these guys will always ignore the presence of a higher up unless who knows, witnessing a romance between a teenager and a bird maybe?
Overall, i will definitely not renember this exist
