Lady Solea's family can't figure out how she lost her memories or why she keeps raving about her "jackpot." They don't realize she's actually Yoon Jiyoon, a lottery winner who was suddenly brought into their world! Determined to return to her reality and claim her riches, Jiyoon sets off a series of shenanigans to send herself home. Yet when Solea's family proves more fun than expected and distracts her from the mission to leave, Jiyoon begins to wonder if family is worth more than a fortune...

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!
