The child I pushed + welcome to the classroom of strength supremacy + Ling Xiaolu Kiyotaka + harem (toolbox) Ling Xiaoji Kiyotaka from the White Room accidentally traveled to the world of the children I pushed, and became the child of Hoshino Ai, becoming the eldest brother of Aqua and Ruby. Hoshino Ai: "Hahahaha... Kiyotaka, what's your expression! It's so funny!" "Look at your younger brothers and sisters, how dedicated they are! Why are you the only one who is so serious as if you are in a board meeting?" Hoshino Ruby: "I want to be an idol like my mother." Hoshino Ai: "The director said that you are very talented and wants you to receive more professional training. Mom wants to hear your ideas." Aqua: "I do." After Akane Kurokawa finished confessing her love to Kiyotaka, she looked at Kiyotaka with a blushing face. Ling Xiaolu Kiyotaka: "But Akane, I have never regarded you as a companion. You, Aqua, or anyone else, everyone is just a prop to me. No matter what the process is, no matter how much sacrifice I make, as long as I achieve my goal, as long as I am the one who wins in the end, then it will be okay. "
