I, Rose Hailon grew up to be a noble princess. One day, when Cecilia, a friend of mine, becomes my foster sister, she took everything away from me right under my nose. I was deprived of my status as a princess and eventually had to choose death. I died all alone. But what kind of God’s prank is this? After I opened my eyes, I’d gone back to the day Cecilia became my foster sister… This is an opportunity that might never happen again. So… ‘Cecilia, I swear I’m going to take off your mask and I’ll start today.’
