Zongman: The child next door was picked up by Qiong and taken home

As an ordinary 2D time traveler, when Maki Yusheng saw the silver-haired girl who picked him up and took him home, he thought the world he traveled to was the famous "Yuen x Sora" in his previous life.
When he was writing light novels and saw a certain blonde loser, when he was drawing comics and met a certain three-no girl, and when he saw the Service Club and Shinomiya Kaguya at school, he thought the world he traveled to was the world of souvenirs.
It was not until he saw the beautiful girl next door named Yotsuya Miko and the huge yet distorted bodies spreading outside the world that he understood the nature of this world.
Ever since——
Mu Yusheng could only take out his own golden finger and shouted: "System, add points!"
