Ten years ago, Song Lichen said to Lu Qiyi, Xiaoqi, I did something wrong, can you forgive me? She looked into his dark eyes and nodded. Then, when she left, he said to her, actually, the person I hate the most is you. Ten years later, Lu Qiyi, who grew up and had a family again, lived a happy life. She was so happy that she almost forgot about him. She had parents, school and friends, a group of people who loved her, and He Heechul. However, fate is a kind of strange circle, which is round and round but can never get out. When Lu Qiyi was eighteen years old, she met a man who could play the piano, cook, drive a racing car, and fight. Three letters, 671, were engraved on his wrist.
