Shen Yu'an traveled through time twenty-eight times. Every time he went back in time, he tried to save that person.
Stop Shen Jianguo, take another route, and call the police in advance.
Failed every time. Every time he wakes up, he forgets one more inch:
The angle of the man's fangs when he smiles, the rising sound of his voice when he says "see you tomorrow", and the way he stands under the streetlight waiting for him in the summer evening.
The twenty-eighth time, he finally understood.
He kept going back, not to save, but to say goodbye.
In front of the young man, he told all the truth: "I tried twenty-eight times, and every time I watched you go to death without changing anything."
After hearing this, the young man only smiled and said: "Shen Yu'an, please accept my departure calmly."
This time, he wasn't trying to change anything. He walked with him through the last stretch of the road, made up for the "goodbye" that had never been said, and then came back with memories and woke up in the morning light.
The door to the old room is still closed, but the pen with the word "Chi" engraved on it can finally be used to go back to the past.
Concept: Time is one-way, but love is not
