“My parents will sooner kill me than have me be anywhere other than Slytherin.”
“Oh”, Remus didn’t know what to say. Luckily, before he could get a word out, the door behind him opened and people started to filter out.
Sirius got up, tightened his neckline again and stood up straight, with one more glance at the door, almost as if he was making sure that no one was around yet, he asked, “Will l see you at Hogwarts, then? I’ll feel better if I’ve already made a friend.”
Or, a series of glimpses into Sirius and Remus' relationship throughout 20 years. Always on the same day. (A One Day inspired AU)
