gemma ✧ l.s
harry has been interested in louis for as long as his little heart can remember; a week after his sister, gemma, had introduced a pretty boy named louis tomlinson as her new boyfriend. harry was only nine at the time, louis being seventeen, and they grew to become somewhat close friends.
both grown up now, louis and gemmas' relationship is still going strong. they're due to be married in four months, though harry doesn't really like to mention that.
so what happens when your brother and soon-to-be husband start becoming a little too close?
