Ron, Hermione, and I were in Hogsmeade on an average Hogsmeade weekend during our 6th year. Then we walked into the Three Broomsticks and who are the first people we see? Dean and Ginny.
Dean was holding Ginny's hand while using his thumb to caress her hand underneath his. Smiling at Ginny and talking to her probably about Quidditch or something while his thumb kept going back and forth across her hand, occasionally stopping to rub circles on her hand.
Harry could only see red lights flashing before his eyes. Harry was seeing red. He was enraged with, dare he admit it, jealousy. His body wanted to walk over to Dean and punch him in the face until he was unconscious for holding his girl's hand. Unfortunately his brain banished the thought from his mind before he could act on his instinct. Mine. She's mine. A hissing sound came from deep in Harry's chest.
Harry and never really considered himself to be very possessive of the girls (well really girl) that he dated, but this was different. Harry was jealous of Dean. There he had admitted it. He was jealous of Dean because he got to hold Ginny's hand whenever he wanted to. And usually didn't have Ron breathing down his back like he would if it were Harry who was holding the soft delicate hand in his own.
Harry wanted so badly to go over to Ginny and wrap her hand in his own and talk to her and flirt with her which always made her cheeks go the famous Weasley red.
"Harry, are you alright?" Hermione asked him with concern evident in her voice.
"Yeah. Yeah I'm fine Hermione." Harry replied hastily, his eyes never shifting away from the red headed angel with flaming red hair that practically danced and taunted Harry every time he got anywhere near Ginny.
Harry supposed that he couldn't call his feelings for Ginny brotherly anymore or strictly platonic either. He liked Ginny Weasley. He just had to find a way to get her away from that git Dean Thomas.
