I became a millionaire when I turned 10 years old. It has been 10 years since I reincarnated as an extra in a novel. The day my grandfather, the owner of the house and the one who raised me, passed away,Something came from the infamous ducal family Vlasco'."His Excellency, the previous Duke, gave his entire inheritance to Miss Katisha..""His Excellency, the former Duke...?"So, my grandfather was Duke Vlasco?! I was happy to inherit a huge inheritance for a moment, but there was no way the Vlasco family would leave me alone, even if I was not related to them!!"No, I have no specifications...""Cash, excluding inheritance tax and personal vaults at the central bank,Everything else that is in Vlasco's name remains as is."You can just tell me.""I'm going!!"Now that this has happened, let me see to the end of my money! I am the number one snob who risks her life for money.+
