QT Arc The MC is kept as a concubine by the ML who is Emporer. The ML had to marry an Empress and stopped visiting the MC. The ML had gifted some jade "toys" to the MC and when the system told the MC is was time to go, the MC asked to bring the box of "toys" with him as they were worth a lot of money. When the MC transmigrated into the next world he found out the system didn't take the box with him. Also the day the MC left (and his body in that world died) was the day of the ML wedding to the Empress.
