The emerald bracelet my mother gave me in my previous life was bound to the exchange system, and my slender fingers were exchanged for my sister. I ended up miserable and couldn't have enough to eat. After rebirth, I pretended to accept the bracelet and put it on the octopus in the aquarium. My sister's fingers are getting longer, but she doesn't know that they are about to turn into tentacles. My adoptive parents wanted to marry me off, so I decisively planned a future for myself. Can I win this game of luck?
