May 2nd, 1971, three years after Bellatrix Lestrange graduated from Hogwarts
"… you may now kiss the bride."
Rodolphus leaned in to kiss Bellatrix on the lips. Reluctantly, she kissed back.
Married, already. Hardly out of Hogwarts, and married… To a man I barely know, no less. Bellatrix watched the crowd rise out of their rows, one by one. It was almost as if there was a line waiting to congratulate Rodolphus and Bellatrix on their "lovely and gorgeous wedding"
They were the last to leave the church several hours later. Dark clouds began to roll across the sky, fitting Bellatrix's mood perfectly. Not Rodolphus', though. His smile went from one ear to the next, as nothing could put a damper on his wedding day. Bellatrix recalled the countless times at Hogwarts he had asked her on dates, and he was still the same big-headed, arrogant fool that he was today…
"Black! Hogsmeade. This weekend. Meet me there?" Rodolphus grabbed Bellatrix's shoulder.
" No thanks, Rodolphus. Quidditch captain or not, I still don't fancy you." Bellatrix glared at him. Rodolphus was 'perfect'. Head Boy. Prefect. Pure-blood. Everyone fancied him.
"C'mon, Bells, just one day!" Rodolphus gave Bellatrix a 'charming' half smile. She thought it looked more like he had just swallowed a toad.
"Rodolphus, I wouldn't go on a date with you for all the galleons in the world! And don't call me Bells!" Bellatrix stormed away from Rodolphus as the bright sun shined in her black hair.
"So who do I need to thank for your lovely hand in marriage, Bells?' Rodolphus nudged Bellatrix and broke her train of thought.
"My father. And I prefer Bella, Rodolphus." Bellatrix hadn't spoken to her father since the beginning of her seventh year, when he told her he had arranged a "respectable, pure-blood marriage".
Just because I didn't fall in love with anyone at Hogwarts doesn't mean I'm a blood traitor! She thought angrily.
"Bella, did you honestly want to marry me?" A troubled look hit Rodolphus' face.
Bellatrix had been dreading this question. "Rodolphus, I hardly know you. My father arranged this marriage to preserve our family trees."
"You talked to me at Hogwarts plenty of times! We were even Herbology partners our 2nd year. You can't tell me after all that time of being friends that you barely know me!" Thunder clapped above the two.
"Friends? Wow, Rodolphus, I didn't realize asking a girl out every other day for three years meant you were friends!" Bellatrix shouted. Rain poured down from the sky, finally wiping off Rodolphus' smile. Of course, it wasn't his fault they were married. Her father just happened to pair her with a boy who fancied her.
"Well." Rodolphus gave Bellatrix a quick peck on the check. "If it matters for anything, I always loved you."
Rodolphus' shaky hand grabbed Bella's, and Bella could have sworn she saw a single tear dripping down Rodolphus' dark face as they apparated to The Noble House of Black.
