Screw The Noble Life, I’m Going Home

After confirming that I had won the lottery, I tried to quit my job! However, as soon as I opened the door, I found myself transmigrated into the body of a noble lady. I have one year to claim the prize money, so I have to return home at all costs. Please wait for me, my 1.7 million won! Mum will be there soon, but... What's wrong with this family?! "I love you." But I'm not your daughter! "Sister, you might get hurt so I'll hold you." Did he mean he would lift me? What is this guy, a giant brown bear? "If you mess with our sister one more time, I'll make you disappear without a trace." He's got a pretty face, but he has a sharp tongue. "Don't fall ill." Don't worry about me. Why are there so many of them?! I'm not a noble lady! Leave me alone, I wanna go home!
