I highly recommend omniscient reader's viewpoint especially the novel. it has no harem nor love interest but there is some pretty good team building and every character is op in their own way which makes it really interesting. you have to check it out for yourself to find out.
Good Plot Good Fight scene
Harem is fine as long as i didn't wasting my time reading it
I already read some MANHWA like Solo Leveling So I'm Looking for A Good MANHUA
