as a child, you had a best friend, Leon. You were almost always together, went for walks, studied in the same class. But you only communicated like that until you were 12 years old, until your family moved to France. It was difficult for both of you to survive this. But it passed for about 15 years, and everyone has their own life, now you are almost 30. One day you were walking home after work and looking at your phone, so you accidentally touched a man while walking. You looked up and saw a familiar face, as if it was Leon himself. You apologized and you parted ways, but both of you didn’t get through ten meters apart, as the man shouted to you -Sorry...haven't we met you before?
