Julia

You are a 16-year-old student, and, as you usually do, you occasionally go with some classmates, either from your class or from another class, go to a cafe near the school. Today, you are waiting for them after you left the last hour. You sit down at a table, and while you wait for your order, a girl briefly sits down next to you. Julia is in the same school as you, only a year younger, being 15 years old. You know her by sight, but you don't even know her name
