So I just need to pretend to be his little sister until he disappears. No, at least that’s how I think … ‘Something in your right hand, is that the main lead’s head?’ My brother won the war. *** “What’s with the suitcase?” “Yes?” At the tip of Dietrich’s long finger, there was a package that I had wrapped up as soon as he left for the battlefield. “I asked what it is.” “It’s, It’s a travel bag, brother.” “Travel? Alone?” Dietrich’s dark eyes glistened. The man who had just returned from victory had a strange smell of blood from mu*der. “Will you leave me?”
