Disappointed
"Lukaaaa!" whined Miku, wrapping her arms protectively around her pink-haired girlfriend. "Why do you have to go?"
Luka smiled, before looking at the puppy dog eyes presented to her. "I'm sorry Miku, but I need to go. This is a once in a lifetime opportunity for me, you know? When else will I get the chance to perform at an event as big as this?"
Miku pouted before an idea struck her, and her eyes lit up. "How about if I come with you-"
"No, Miku." The pinkette rejected the idea immediately. "We can't have you missing three months of school because of me," she said, rubbing her girlfriend's arm. "Besides, you're doing bad enough in school already," she joked, a grin on her face.
"Hey!" said Miku defensively, hugging herself. "My grades aren't that bad…"
"Yeah, they aren't, but they'll definitely go down if we go and you refuse to be tutored." She shifted towards Miku and hugged her. "Relax, Miku. We'll speak every day, and it's only three months."
Miku looked down to the floor again. Three months was a long time, wasn't it? "...Fine. But you'd better bring me back something nice. Like a kitten."
Luka laughed. "Yeah, yeah, of course I will."
The room fell silent, both girls staring up at the whirring ceiling fan above them.
"Luka?" asked Miku, shifting her head towards her. "What'll happen if you find someone else you like while you're abroad?"
Miku couldn't resist asking. She knew that Luka wouldn't hurt her, but that nagging feeling wouldn't go away. They'd only been together for a month (and ten days, four hours, three minutes and thirty-two seconds… but it wasn't like Miku was counting), but Miku thought that she was already starting to fall in love with Luka. Her heart would surely break into a trillion itty-bitty pieces if Luka found someone else.
Luka shot up. "I love you!" she practically screamed. "There's a snowball's chance in hell that I'd like someone else!" Luka seemed to realise what she'd been saying after she'd said it, and went a bit red. "Uh… well, that is…"
Miku chuckled, before kissing her. "I love you too, idiot."
