Angels are pure and innocent, but their tears make people feel sad. What made the angel shed her flawless tears, and what kind of story is there in the tears? Whenever night falls, a girl with long hair will always be seen in a corner of the square. She always looks at the passers-by with a smile. The wind blows her long skirt, making a jingling sound. The most noticeable thing should be the various small bottles in her hand. "How much does this wishing bottle cost?" "Can I ask you what you want to do with it?" "It's a lot of nonsense to buy a bottle. Of course it looks good, so I bought it to play with. How much does it cost?" "Sorry, I don't sell it." "Then why are you standing here, crazy!" The girl still kept smiling, and no one else understood this strange dialogue.
