A young man in a black cloak stood at the corner of the street with a cigarette in his hand. He looked a little annoyed. Beside him was a girl in a black down jacket who was looking at him with dissatisfaction. The man looked up at the girl and lit a cigarette. He took a deep breath and the smoke filled the air around him. His eyes were cold as if he was thinking about something. The girl walked to the man and patted his shoulder gently. Then she asked,"What's wrong with you?" Is there anything bothering you?" The man raised his head and smiled." Actually, I've been thinking about a question recently. I don't know the answer." The girl laughed softly. What's your answer?" The man was silent for a moment and then said,"I don't know. But I have to find the answer or I can't continue to live." The girl patted the man's shoulder and said,"I understand what you mean, but this problem is not just your problem." Let's go and find the answer together." The man looked at the girl and nodded. The two of them walked down the street hand in hand and began to search for the answer. They walked for a long time through the bustling city and finally arrived at a mysterious place. There, they found the answer and also discovered a new problem. They began to think about how to solve these problems and how to deal with new problems. In this process, they supported each other and moved forward together. In the end, they found the answer and their own direction.
