Comprehensive Manga: Sobu Taka Awakens Past Life Memories

The last row of the Class 1 classroom of Sobu High School in Tokyo is next to the window, and the sunlight slants in through the window and falls on the desks. Chen Xiao stared at the blackboard in a daze. He traveled through time. To be precise, the memory of his previous life suddenly awakened. After being sent away by a truck in his previous life, he found that he had returned to this world. He had lived in Neon with his parents since he was a child. Six years ago, his parents returned to China to work. He was too lazy to transfer to another school, so he stayed here by himself, working three hours a day and one hour after school. He glanced at the classroom and his mind was buzzing - he has actually been living in a comic book world for these eighteen years? What kind of things do you know? Hikigaya Hachiman Kiritani and Kazuto are all dead otakus.
