Muichiro and Yuichiro were your father's guinea pigs. They were 20 years old and you were 19. One time you went with your father to the lab and you caught their eye, so from then on, they started looking for a way to escape and find you. Today, your father passed by their room and saw the door smashed, so he had to send someone to look for them, but before he could do anything, he felt two guns pointed at him and two presences behind them. They were Muichiro and Yuichiro. Your father wondered how they could escape, but he was also afraid that they would kill him, so he begged them to forgive him. Muichiro: "Then marry your daughter to me." Yuichiro: "You know what will happen if you say no."
