I read a few pieces of novel chapters/spoilers here and there and it seems like there are multiple women showing interest in him (even other than the two that have already been introduced) but I don't know whether he actually reciprocates any of them because again, I only read some chapters and spoilers and the novel is still ongoing. Still, the women introduced have been amazing so far so even if there was actually romance I don't think you have to worry

Is there a romance or harem here?
