An Unexpected Return [Reborn]

"Keep heading west, cross the twilight line, cross the International Date Line, and return to the day we first met." Physics prodigy Sheng Yuan became Qing University's youngest professor at the age of twenty-seven. He never imagined that one day he would be stumped in class by a student and the theory he himself had proposed. The student asked: Many people say that the Fourth Space Theory you have devoted yourself to researching is nonsense. If it really exists, what would you most want to do after falling into the Fourth Space? Sheng Yuan had considered this question countless times. If he happened to fall into the Fourth Space, he would make sure to hold Lu Qingxu's hand tightly that day. * In high school, Lu Qingxu always had bruises on his face. He sat alone in a corner, his expression frighteningly gloomy, and never interacted with anyone. No one at No. 1 High School ever dared to provoke him. They all went out of their way to avoid him. But Sheng Yuan had seen Lu Qingxu crouching by the flowerbed, gently petting a stray cat as it ate, his expression kind and his lips curved in a smile. He had also seen Lu Qingxu's face turn bright red as he confessed his feelings, his hand trembling as he offered the love letter, before he fled in embarrassment, moving his arms and legs in sync. When news of Lu Qingxu's death spread, everyone was relieved they would never have to see that jinx again. Only Sheng Yuan lay awake at night, quietly crying as he stared at the unfinished text message. * An accident during an experiment sends Sheng Yuan back to the afternoon when Lu Qingxu confessed to him. Ignoring his teacher's scolding and his classmates' astonished looks, he runs out of class. When he sees the boy from his memories in front of the school flowerbed, he slows down. Fighting back his emotions, he manages a smile and calls out to Lu Qingxu: "Lu Qingxu, do you like me?" Lu Qingxu turns around and sees Sheng Yuan. His face immediately burns red, and he gets so nervous he doesn't know what to do before fleeing in embarrassment.
