Harry says faster than he's talked before. It's quiet for a long while, Louis just staring at Harry with his mouth agape. Harry doesn't know what to do now that he's finally told Louis.

I am in love with your sister." ------------------ An AU where a vulnerable Harry has fallen in love with Louis, his sisters mischievous boyfriend.
