While barely surviving as a wizard child soldier on a brutal battlefield, the memories of my past life suddenly returned. And I realized this world is the setting of the novel <The Sword Planted on Ruins>. Of all things, I possessed a body inside a war novel doomed to an apocalyptic massacre ending?! If I want to avoid that horrific conclusion, I have only one choice: stick right next to the “hero,” Leviathan Zebert, and make sure he doesn’t die. “Mister, does your family happen to need a youngest child?” After countless twists and turns, I somehow succeed in becoming the youngest member of the Duke Zebert family. But the problem is… I’m a wizard—the very thing Leviathan despises, a deserter child soldier, and to make things worse, my gender got misunderstood. If I don’t want to be exposed and kicked out, I have to be careful. Extremely careful. Yet this family never leaves me alone for even a moment. I’m already busy trying to find a way to protect Leviathan, but first—strawberry cake. Yeah… it’s delicious! The soft bunny-fairy booger of the Northern Grand Duke’s household <The Youngest Is Hiding a Lot of Things>
