The man who raised Fifteen was his master, who made a living by telling fortunes. To put it bluntly, he was cheating.
Fifteen will always remember that day. He walked out of the kitchen and asked his master why he came back so late.
The master laughed happily and said that he had brought his wife back.
It was only after many years that he realized that his master was really capable.
Intention: Some fates are already destined.
