[Fgo] My Younger Brother Rehoboam and My Adoptive Father Solomon Beat Goetia. After All, This Chaldea Belongs to My Old David's Family.

An accident puts 17-year-old Li Xiang on the road of no return to save the world. The combination of the male Ritsuka and his younger brother Rehoboan, paired with his old father, Dr. Roman, is a short story pulled together into a complete novel. The plot only reaches the singular point of the ending and then ends, while the plot of the second installment is completely gone. My question is that the author is a die-hard and only likes plots involving doctors. Concept: An adventure story turns into a family ethics drama
