A world where science is a little more advanced than it is today. A humanoid android, commonly known as "Giftia," which is manufactured and managed by the world's largest company SAI, blended into human society and lived with people. However, it is only allowed for a limited time. 81920 hours-that's the life of Giftia. Is the collection work of Giftia, who spent an irreplaceable time with the owner, just a job to tear up memories ...? Tsukasa, Zack, Shelley, Connence, and Islay. A collection of gems depicting "Thank you from the bottom of my heart" that each encounters.
