An Abandoned Woman and Three Children

I have to say that I caught up with the trend and played time travel, but I was told that this was just a dream, a very long dream, and that the dream would end as long as death. All right! I am a person who is afraid of death, so I decided to play around with dreams, but my luck is a bit bad. The randomly selected identity turned out to be the mother of three children, and she was also a concubine.
