She had just turned 16 that year, and like many girls today, she thought she had liked many people, including the handsome guy at the same table, the nerdy guy who ranked first in every grade, and the athletic guy who went to the same school as her. She thought she had liked many people, and she thought she was a member of the army of puppy love. But until she met her, she realized that it didn't even mean liking him. If it was love, and then she gradually lost contact with those people, why was she not sad at all? In those years when she left her hometown, only when she thought of that person, she would suddenly stop everything she was doing and sit in a daze quietly. Now she occasionally goes to KTV and jokes with her friends about what she thought she liked at that time: "Hey, at that time, I didn't know what love was." After saying that, she cried and said softly: "But now I know, I know." What is love? She said, love is when you know that you will not like anyone else except her, you know it with certainty.
