One Thought of Being a Concubine: Take the Prince to Hunt for Souls

After rebirth, I thought everything was calm, but unexpectedly, I was in crisis everywhere. Why? She was originally an orphan who was reborn in a fire, with a stunning face, but she was ups and downs in troubled times, looking for the truth about her rebirth; He was originally the son of a prince, with great splendor and wealth, and a capricious killing spree, but he was willing to give up everything for her and help her fulfill her wish. In order to search for the past, she and he are destined to meet. In this conspiracy, is he using her, or does he love her... In one thought, I got acquainted with my son; In one thought, I parted from my son; In one thought, even if my soul is gone, I am still willing to meet you.
