A/N: This may be slightly AU. There isn't much known about Seamus and Lavender. This is written for the Monthly Het-Tastic Drabble Athon with the prompt "wish upon a star." It was also written for the number of your pen name challenge, and the As Strong as We Are United III competition. It might turn into a collection of Seamus/Lavender moments.
Lavender was working on her astronomy homework at the Astronomy Tower late one night. She stiffened when she heard footsteps coming up the stairs, and reached for her wand. The footsteps grew closer, and she raised it as she quickly thought of a spell to defend herself. Her wand nearly fell when she saw that the person was Seamus and smacked him across his shoulder.
"Hey! What'd I do?" Seamus exclaimed as he held up his hands in protest.
"You scared me. I thought you were Death Eater or a Slytherin," Lavender answered as she let out a sigh of relief.
Seamus crossed his arms as he stared at her. "It serves you right for getting scared like that. You shouldn't be out here this late."
Lavender narrowed her eyes as she crossed her arms as well. "Neither should you! What're you doing here?"
Seamus sighed as he met her eyes. "Parvati was worried about you. She woke me up when she realized you weren't in bed and I decided to look for you."
Lavender relaxed as she went back to her books. "I'm sorry. I'm fine. You can go back to bed now though," she said as she gazed back at her books.
She glanced up when she realized that Seamus didn't budge. "I don't want to leave you by yourself. It's dangerous, especially at night."
Lavender's heart flipped when she realized that Seamus actually cared about what happened to her, but she ignored it. She couldn't let her old feelings for him come back now. "Why do you care? We haven't really spoken in three years," she snapped at him.
Seamus looked at the ground uncomfortably as he shifted from one foot to the other. "I just…do, all right?"
Silence grew between them, and Lavender made room for him to sit down. "You might as well sit," she muttered quietly. "I'm going to be here for awhile."
Seamus stood there quietly for another moment before he joined her. "I'm sorry for how things went after the Yule Ball," he said finally after several moments.
Lavender glanced up at him and was startled when she realized that he meant it. "We used to be best friends," she said finally. "What happened?"
He shook his head and shrugged. "We just…fell apart. We were young. It was stupid. The thought of a relationship scared me at the time."
Lavender sighed. "I didn't want a relationship then. I just wanted a date with somebody I knew," she admitted.
"I didn't know that then," Seamus answered defensively. "I'm tired of avoiding you all the time. Can we be friends again? Please?"
Stars twinkled above them as Lavender looked up at them as if she was searching for the answer. She nodded before saying, "Don't let me down again."
Seamus grinned at her as he hugged her. "I won't. I promise."
Lavender gave him a look, but decided to look up at the sky instead of replying. A shooting star appeared and she quickly closed her eyes to make a wish. When she opened them, she saw that Seamus was still staring at her. "What'd you wish for?" he asked her quietly.
"It won't come true if I tell you," Lavender answered, smiling at him as she snuggled against him to stay warm.
