(Operation Red Sea) What Is a Promise?

The author says: I've wanted to pair the captain and Xia Nan for ages.

I searched and found nobody had written it, so I'll do it myself.

Updates irregularly.

Military experts, don't come here to argue with me.

Main pairing: Gu Qing and Li Dong

Side pairing: Yang Rui and Xia Nan

Xia Nan gets a redemption arc. If you don't like it, don't complain, just click away.
