Her name is Lingzi, a girl with a stubborn personality. Reiko's body was underdeveloped, but her psychology was too precocious. Her first love was not a beautiful memory, but an unbearable mental torture. After finally getting out of that environment, she thought she was free, but she didn't expect that fate would be against her and make her meet him again, starting a longer entanglement. Reiko never wanted to admit that the relationship between them was love, because it was too far from her ideal love. She could not feel love, only endless entanglement. But looking back a long time later, he was always the one with the deepest memory. Only in the end did Reiko realize that true love is different from infatuation and liking. It is a forced choice from which there is no escape.
