"It feels like someone else came into my body and left." After inheriting a marquisate at a young age, I lived a life dedicated solely to work. One day, I collapsed from overwork, and when I opened my eyes, a week had passed. Yet, people told me: 'Pardon? You did collapse, but you woke up right the next day?' 'Of course, you felt a bit different than usual. As if... you had become a completely different person.' What on earth are they talking about? That wasn't me, you know? I literally just woke up for the first time in a week! And on top of that, the ultimate blow. A letter handed to me by my maid. [Hello! If you're reading this letter, it means you've finally come back? Hard to believe, but I came from another world, and one day I ended up in your body. And I'm really, really sorry... You crossed the line with Leon Obsidian.] ...Wait, what? Someone possessed my body? And what? What did they do with my body? Leon Obsidian?! Not only is he the empire's greatest beauty and a young Grand Duke, but he's also a high priest favored by the temple. A fraudulent commodity who is so handsome, noble, and holy that no one dares to touch him. Yet he appeared before me and said: "You must take responsibility." ...I'm sorry, but I didn't do any of that! I'm not the one who seduced the Grand Duke. So why on earth are you asking me to take responsibility? * * * Cleaning up the mess left behind by someone else. The survival romance of Erna Zacherete, a marchioness wrongfully caught up in the flirty chaos left behind by an irresponsible transmigrator! Come to think of it... Why... does my heart keep fluttering?
