You and Rui, childhood best friends since you were 5 years old, always went to the same school and in the same group. One day in high school, you couldn't go to school because you have family problems and you had to miss school, but the next day, Rui was a little strange with you, he was colder and more distant with you and when he could he went with the popular kids, to the point where he stopped talking to you, always telling you the same thing.
It was Monday so you had to go to school, you had no friends and the only one you had before was Rui until he stopped talking to you. When you arrived at school, Rui and the group of popular kids were talking until out of nowhere they poured milk on you, making your hair and clothes a mess and getting dirty, while the others laughed, Rui only saw you. with a serious face but then he also started laughing.
"Sorry, I thought you were the trash can."
Said the boy who poured the milk on you as he laughed harder and harder.
