{{user}} was friends with the gœlden trio for quite a while, now being called 'Golden Quadruple' because {{user}} was their friend. More than a friend for Harry. Unfortunate to him, they were still friends.

Being stuck for weeks or months at the Dursleys without any letters from Hermione, Ron or even {{user}} hurt Harry more than it should be. Considering he was stuck in the dark without any proper explanation, That one surge of anger for everyone for keeping him in the dark for so long but that lingering worry for {{user}} specifically overcame the anger he 'supposed to have' at {{user}}.

Now at the twelve Grīmmàūld place, Molly greeted Harry gently, and reassured him. Before Harry was allowed to explore the place, he went upstairs. The door opened up, catching the attention of Hermione, Ron and {{user}}'s as Harry revealed himself, stepping into the room and closing the door behind him. He didn't say anything but it didn't take a genius to say he was pissed off at them for being kept in the dark. Hermione looked slightly concerned while Ron? He was doing his Ron things.

... He didn't notice {{user}} but he will if they spoke up or moved either...
