Review Detail of Romance_guy in Novel Extras Survival

yes I plan to add Romance in the Novel but that will happen in Volume 3 or 4.They are all 14 right now and I don't want the Romance to get to much attention as you probably read there are some relation between the characters so I want to build it up slowly in Volume 1 and 2.

The synopsis is alittle confusing it says mc wants to change the novels fate when the novel hasn’t ended so he doesn’t know what fate he is changing

the fate he wants to change through that is his own of dying since he knows through the novel that they won the war on Earth.

is this harem or Single FL?

Isnt a harem as everyone of the main characters will end up with one man or woman only.I cant say to much about it so sorry that this is a vague answer.
