She was reborn in the war novel as the sister of the villain who had never shed blood nor tears. The person acting as my ‘brother’ was a villain who, after losing the war, would be sealed away by the male lead. So all I have to do now is pretend to be his sister until he later disappears. Or so I thought… ‘What’s that in your hand? Don’t tell me that’s the male lead’s head?’ My brother won the war. ** "What's with that suitcase?" "Huh?" Dietrich's fingers tighten on the luggage that I had packed as soon as he left for war, "I asked you what this is." "It-It's a travel suitcase, brother." "You want to travel? Alone?" Dietrich's dark eyes sparked with violence. Having recently returned from war victorious, he sure smelled like a bloodthirsty killer, "And leave me behind?"
