Gong Junichi Watanabe started his love affair with two girls in the first person. Watanabe's second lover Naoko was originally the girlfriend of his high school friend Muyue, but later Muyue committed suicide. A year later, Watanabe and Naoko met unexpectedly and started dating. At this time, Naoko has become demure and shy, and a shadow that is difficult to capture passes through the beautiful crystal eyes from time to time. They just walk aimlessly in the streets of Tokyo, falling leaves day after day, either before or after, or side by side. On the night of Naoko's 20th birthday, they had sex, but Naoko disappeared the next day. A few months later, Naoko wrote that she lived in a mental hospital in the distant mountains. At the same time, Watanabe met Yoko in a small restaurant near the school. Yoko borrowed his lecture notes on History of Drama 2 and later got to know him. Later, when Watanabe visited, he found that Naoko began to have the fullness and beauty of a mature woman. Watanabe also met Reiko Kobayakawa in Naoko's dormitory. Before leaving, Watanabe said that he would wait for Naoko forever. After Yoko's father died, Watanabe began to associate with Yoko in the lower grades. Yoko is just the opposite of Naoko. It's like a deer jumping into the world in the morning light of spring. During this period, Watanabe was very depressed and confused. On the one hand, I can't forget Naoko's lingering pain and tenderness, on the other hand, I can't resist Naoko's bold confession and charming vitality. Soon came the bad news of Naoko's suicide, and Watanabe went hiking around without soul. Finally, encouraged by Naoko's roommate Reiko Kobayakawa, she began to explore her future life.
