There is often a situation where, on two different railway lines, two trams head in the same direction and stop at the same platform.In Tabata, the Yamanote Line to and from Shinagawa and the Keihin Tohoku Line are just that. When he was a graduate student, Takashi Tsuruga took the Yamanote Line three times a week, and his destination was the university reference room in Shimbashi.He takes the same tram every morning at a fixed time.Although he passed the rush hour, he still had no seat. He was standing by the door all the time, always in the same car and the same door. He looked aimlessly at the scenery outside the window: disorderly buildings, gray sky, poor-quality billboards.

However, these views are often blocked by the Keihin Tohoku Line coming in the same direction. The train approaches and departs from time to time, flying in the same direction at almost the same speed.When the two trams are closest together, they seem to be integrated into one body, and even the appearance of the passengers on the opposite side can be seen very clearly.Of course, no matter how close the two parties are, they cannot communicate, and they just sail towards the end of the journey. One day, Chongshi's eyes fell on a young woman in the opposite carriage. Like Chongshi, she stood by the car door and looked out the window. She was a girl with long hair and big eyes.Probably a college student, Chongshi deduced from her casual attire.

Then every Tuesday, she will inevitably appear on the opposite tram.The same moment, the same tram, the same carriage, next to the same door. And Chongshi began to look forward to the arrival of Tuesday slowly. As long as he saw her, he would feel inexplicably happy all day long.On the contrary, during the days when he couldn't see her, he suddenly became at a loss again.All in all, he's in love with her. A few days later, Chongshi made a major discovery. That is, she seemed to be watching herself. The two car doors were close to each other for a moment, and the two were almost standing face to face.

Of course Chongshi kept staring at her, as if she was also looking at him at that moment, for just two or three seconds, the two of them looked at each other through two glass windows. Should I smile at her? Chongshi hesitated, but failed to act.Because he thinks that it is very likely that the other party's looking at him is just an illusion, and she is just staring out of the window. In the end, Chongshi had no choice but to pretend that he didn't pay attention to her at all, and stood by the door, and she didn't send any signal after that. After nearly a year like this, Chongshi found a job after finishing his master's degree.Needless to say, he will no longer have the opportunity to ride the Yamanote Line on Tuesday either.

Last Tuesday, he was ready to take a risk. He is going to take the Keihin Tohoku Line once.Then he stood where she had been standing, and approached her who could only look through the window once.How would she react, be surprised, or completely ignore it?Just thinking of this made his heart beat wildly. What I didn't expect was—— She didn't appear there. He thought he had mistaken the carriage and walked back and forth in the tram, but he didn't find her.She didn't get in the car. Frustrated, Takashi returned to his original position. Outside the window, he saw the Yamanote Line train he had been riding on. The tram looked like this, and he stared blankly.

When the two trains approached slowly, his eyes widened.On the opposite tram, he spotted her figure.Her gaze didn't turn here, but she walked slowly in the car. Chongshi got off the train at the next stop, hurriedly changed to the Yamanote Line, and started looking for her again. However, she who should have been here just now has disappeared.Chongshi ignored the strange eyes of the passengers around him, and walked back and forth in the narrow carriage.Although it was only March, the sweat on his forehead kept flowing. Still can't find her, she disappeared like a mirage. Chongshi looked out the window, and the Keihin Northeast Line slowly drove away into the distance.

Maybe she and I came from two parallel worlds—— he thought so.
