Riza sat on her couch with her little dog, a stack of paperwork and a glass of wine on the coffee table in front of her. Lost in thought, she started when a knock on the door roused Black Hayate from sleep and he leapt off the couch and barked. She rose and walked to the door and looked through the peephole.
Outside stood Colonel Mustang, his handsome face scowling at the ground. She opened the door.
"Colonel Mustang," she said, keeping a tight grip on the doorknob with one hand.
"Lieutenant Hawkeye," he replied, and leaned against the doorframe looking down at her, his eyes a little unfocused. They stood this way a moment, then he stepped forward and kissed her, putting his arms around her and drawing her close. Without releasing her hold on the doorknob she raised her other hand and ran her fingers through his dark messy hair, then grabbed a fistful as she kissed him back hard. Riza felt as though a fist were squeezing her heart. Collecting herself, she let go of his hair and pushed him away.
"Colonel, sir, with all due respect, please leave."
He took a step back, disappointed, and she shut the door in his beautiful face.
Riza took a deep breath and turned back to her empty apartment. She grabbed her wine off the coffee table and downed it in one gulp, then picked up her little dog, held him close, and cried.
Colonel Mustang turned up at her apartment like this once every couple months or so, usually more than a little drunk. Most of the time she kicked him out, but every once in a while, when she was feeling especially lonely and vulnerable, she would let him in. Then they would kiss and pull each other's clothes off and have brief and disappointing sex. Afterward, depending on how drunk he was, he would either leave immediately or roll over and fall asleep. They would barely speak a word to one another, and the experience always left her feeling unsatisfied and sad and terribly alone.
"He treats me even worse than those girls he dates and doesn't care about," she thought to herself. "At least he buys them dinner and flowers before he fucks them."
She knew that the reason he kept coming over was probably that he was drunk and horny and couldn't find a date that night, and that he knew she might let him in. But a small part of herself firmly believed that he kept coming back because deep down he still loved her, and one day he would come back to her completely; the sweet beautiful boy she'd fallen in love with.
And that was why she continued to stay by his side, working with him, protecting him in combat, and supporting his political ambitions. Because no matter how callously he treated her, she couldn't bring herself to stop loving him.
Note: Thanks for reading! This is my first fanfiction. Feedback appreciated. Also I'm terrible at titles, this needs a better one.
