I Still Remember

Louis used to date Harry's sister but when he broke up with her everything changed. He says he has a reason, the reason being that he's gay but he doesn't want everyone to know, definitely not Harry because he would just say he used her.

Harry misses hanging out with Louis, but when they finally start talking again he starts to like him...a bit too much. Does Louis feel the same way? Does he still remember all the fun they used to have?
