Harem

Harem, although I don’t really mind this one becoming one considering it was originally an academy(I think if I remember correctly) game which would obviously have love interests and romance routes or smn

Is it heavily implied harem like the girls are all over him blushing or just casual girl friends?

If I think I’m responding to the correct Manhwa right now, his group is like mostly girls, and many of the characters that are like key players in the main game before he came, the only 2 male guys (I remember) in his group are like the sword prodigy and necromancer
