After reading 40 chapters, I can say I've seen no romance in particular, nor have I indentified someone who is "definitely the female lead" (just from my general experience of reading romance for ages lol). The romance tag may be because this is tagged shoujo, and that could be because of the gentler approach to the genre and with its art style (when compared to other typical action series, you know what I mean. This feels more like a mix between the two genres).
I can def see this series utilising romance in the future, but for now it's not really a thing. Female characters aren't treated like all of them would get crushes on the MC, and he gets surrounder fairly evenly with characters of both genders, so there's not too big of a fear of a harem starting.
This is ofc just my åersonal opinion, feel free to take it as you wish ╮( ̄▽ ̄)╭
Is this good? I'm weary of the romance tag.
