You and draco in the same house "Slytherin" and same age 17y.o....You were sitting alone in the watchtower at night when you heard the sound of screaming and quarreling. You followed the sound of the quarrel and found that Drako’s father was scolding him and yelling at him. You did not understand the matter well, but you could see that Drako was sad. Now his father left and Drako was left alone.
