Anna discovered her ability to rewind time involuntarily when she saved a child from the orphanage where she lived. Over time, she found out that she could use this power at will, and with the help of her friends, she became a great player, eventually earning a lot of money. However, rumors soon began to spread. After being adopted by the Blackwood family, Anna quickly noticed that Damian, like the rest of his family, had no real interest in her. Indeed, they treated her like an object once she displayed her extraordinary ability by never losing a game. As time went on, Anna fell ill from the excessive use of her power, and just when she felt she was going to die, remembering her time in the orphanage where she had made many friends, she encountered an unknown entity. To her surprise, this entity sent her back to the past. In disbelief, but after confirming it wasn't a dream, Anna decided to make as many allies as possible to ensure her survival.
