MC: The Road to War

Female protagonist, weak in the early chapters.

At first, she and My King are on opposing sides.

An original world setting.

Official pairing: Steven and Alex.

I ship CHC (C and HIM).

Those who dislike these pairings can still read it.

(It's not apparent in the main story that they're couples. The SA extras might have some plot?)

Most of the protagonists have chapters told from their own perspective, as part of the original world setting. My King gets little screen time early on. The author's writing isn't very good, sorry if it makes your eyes bleed.
