I once had a very sad love story. We met in a coffee shop on a rainy day. I ordered a cup of coffee and he came over and asked if I wanted to add sugar. I agreed. We started to chat, and gradually I found that he was a very interesting person, so I began to like him. One day, he told me that he had an important appointment and couldn't be with me. I felt very sad but still gave him my blessings. A few days later, I found out that he actually didn't break up with that girl but got together with another girl. I was very sad but I understood his choice. From then on, I started to distance myself from him and stopped talking to him. I know I've lost him, but I don't want him to feel uncomfortable. I hope we can stay friends, but I know it's impossible. This love story made me feel very sad, but I also learned a lot from it. I understand that love isn't everything. I have to learn to let go and cherish my friendship.
