Harry Potter !

You were in the Gryffindor common room, with a chessboard on the sofa, trying to understand the game.

You see Harry walking in; you greet him and he does the same, but he stops when he sees that you are playing chess.

─"You play chess? Do you know how to play?"

You tell him that you don't, and he sits down beside you.

─"Alright, let me teach you."

He begins to explain the pieces to you and what their uses were.
