Author's Note: This chapter is too short for my liking, but my writer's block is preventing me from making it any longer. Sorry.
At 4:20 that afternoon, Hermione was seated a table in the library, reading one of her many textbooks and looking for Oliver out of the corner of her eye. He came in a few minutes later, his hair windblown and with leaves clinging to his robes. Spotting her, he made his way to the table. She stood up as he came nearer, meaning to greet him, but he dropped a scrap of parchment on the table.
"You didn't write this, did you?" he asked before she could say anything.
She looked at it. The handwriting was definitely not hers. "Wasn't Harry's half-birthday last month?"
He laughed. "I take it you didn't."
She responded with a shy grin and pulled out her own note. "And you didn't write this either."
He shook his head. "I have a feeling someone's trying to set us up."
Hermione hid her smile with a frustrated sigh and sat down again. Oliver slid into the seat across from her.
"So, why don't we play along?" he asked, a sly grin on his face.
She looked at him quickly and the blood rushed to her cheeks when she noticed he was actually smiling at her. "How?"
He leaned back and casually scanned the room, before turning back to her. "Is that Ron Weasley's handwriting?" He tapped the note she had received.
She looked at it more closely. "Yeah, how did you know?"
"Don't look up," he warned, "but there are two very familiar faces watching us from behind some shelves."
"Ron and Harry," Hermione replied instantly.
He nodded, a barely perceptible movement that she was sure Ron and Harry didn't see.
"Let's plan a half-birthday party," Oliver said brightly.
Hermione laughed. "Ron should've put the same reason on the notes. With different reasons, it's even easier to figure out that neither of us wrote the notes."
Oliver took out a quill of his own and flipped over one of the notes. "What should we do for Harry's party?"
"Are we really having a party?" Hermione asked unsurely.
"Nope, we're just acting like it," Oliver replied. "Now, what should we do for Harry's party?"
As Hermione leaned forward and started making suggestions, Ron and Harry moved quietly towards the door. Ron was beaming.
"I told you it would work," he said triumphantly. "Look at how close they are."
Harry looked back at the pair doubtfully. "I'm not so sure, Ron. I think they figured out your little ploy."
"I don't think so. They probably don't notice anything besides the person across from them." Ron disagreed.
Harry rolled his eyes, but Ron didn't notice. Oh well, Harry thought. Let Ron keep his delusions of success.
I mean, what harm could come of it?
