Resignation LetterWe have known each other for a long time, haven't we?Not a lecture, it seems.It was when I was continuously being defeated at night battles...was it?Everyone was nervous during night battles...I was determined to resign.It was that time, that you burst into my room...That day, when I heard that our flagship sunk at a night battle...YeahThe dark sea, invisible torpedoes, and crashing into comrades.The first time you consoled me......No...I was the one who got nervous.
