I, Kitahara Sosuke, the most regretful thing in this world is joining the navy, no one! What? You ask me why? Oh. How could anyone be accidentally stabbed by a colleague on the battlefield? Where has anyone come home to find that their house has been bombed by their colleagues? Where are some colleagues who ran away for various reasons on the way to a mission? No! 1. This is my first time digging a hole in this novel. Please forgive me if the writing is not good (I don't mind reading Chapters 1 to 3). 2. I don't know what the first few chapters are about, and I will rewrite them later. 3. The CP is undecided, just follow the direction, there is a high possibility that it is someone in the navy. 4. It is inevitable for the characters to be OOC, so just make do with it, they are all poisonous anyway.
