It's probably a false tag because the one tagging just assumes there will be romance at some point, in which there's none. The story itself is pretty short though, it's only 5 novel volumes and I think we're already 70-80% covering the whole story and we just have introduced to the final enemy organization in this chapter, so yeah... It was a kinda rushed ending in the novel too, the author focused more on his other two more popular novels.
This author is very bad at doing romance the only thing resembling romance is in his other series

Don't believe anyone who said the author is capable of doing romance, he's only good at making OP protags fights and adventuring the world, that's it.
