I am considering whether the protagonist in the otherworld has a biological mother who may have experienced invasion by a different race, or if he has a slave mother. The presence of a slave trader in the game exists for the purpose of purchasing slaves. Alternatively, I may keep the current setup where the neighbor's family replaces these roles. These details are still being planned. Additionally, the stable owner's family consists of a father and daughter, which will also play a role in the storyline. The plans for pregnancy need to be adjusted based on the progress of the storyline.
