The Tyrant's Ghostly Doctor's Concubine

He randomly picked up a seven-year-old shota and transformed into the most brutal tyrant in history? If you pick him up, you will have to eat, sleep, and have a baby? Sorry! She has lost her memory. She is a little princess from a neighboring enemy country. Sit down and talk slowly, should he be the princess's consort, or should she be his crown princess? The male protagonist said: "It doesn't matter what the position is. Anyway, we sleep together, and his woman has the final say. He only knows how to pamper her and pamper her to the sky."
