Yi Yi was 68 years old when she died, and she was only 16 years old when she married the Dog Emperor. The dog emperor is seven years older than her.
Her biggest regret in her life was that she died in front of the Dog Emperor and in the position of Queen. She had actually carefully planned her career as Queen Mother, but unfortunately she didn't have time to realize it.
Other than that, she seems to have no regrets. She is neither a good person nor a bad person in this life.
