I can only believe this is leading to the harem route
Yeah this is definitely a harem manga, looking forward for the sex party lmao
I really hope it goes for the full poly route, like instead of harem never committing to anyone, she just has a tangled relationship web with several of the girls. We have so few good poly stories that aren't just a one off threesome doujin but every time I see one that's actually done seriously its peak.
There's so much free real estate left in the story that hasn't been explored yet. Asumi x Mai, will Asumi give up seeing the brothel girls if she does get into a relationship, Nanao meeting Mai, Nanao getting into brothels herself, Nanao/Mai and Asumi going together, constantly baiting the senpai route. It would be a shame to miss out on all of those potential fun storylines and turn into a generic monogamous romance or love triangle story we have an infinite amount of.
