There are multiple female leads, and I'll try my best to avoid being out of character (OOC). Some pure romance anime will also be included, so please don't watch if you can't accept that. Also, some other anime that the author likes will be included as guest appearances, only appearing occasionally and not as regular characters. So please look forward to it. Finally, the main character is an indigenous person.
