This work gives off subtle harem vibes, so I really hope the author doesn't ruin the romantic experience between them by adding threesome moments, especially since they treat each other like everything. Overall, I hope Auriel's jokes remain jokes, but please, could you tell me if you would have a harem or a partner besides them? I really don't want this

I'm still in chapter 120, so I'd like to know, is there a harem in this one or is it just between the twins?

I know this is potentially a stupid question, but there won't be a harem in this work, will there? Is it just the twins? I hope so.
