He is an orphan. Even though he is extremely beautiful, has an alluring appearance, has a photographic memory and a smart mind, and has the best physical fitness, there is nothing in his heart and it is empty. He spent all his time learning knowledge, sports, music, chess, calligraphy, painting, etc. That he had never learned before, but he still could not find the meaning of his existence. He had no such thing as emotion, no matter family affection, friendship, or love. Perhaps God gave him these and must take some away. But God hasn't completely abandoned him yet! He has traveled through time, and worlds are waiting for him to find the meaning of his existence?
