''Gakupo!'' Gakupo turned around, startled, to see who had called him, and caught sight of Rin Kagamine making her way over to him.

Strange. Whatever could she want from him?

''Yes, Rin?'' he asked when she finally reached him. She looked up at him, and he was reminded of Len - they looked that similar, the two twins.

''I heard that you and Miku are together...?'' she asked curiously. Laughing a little, Gakupo shook his head, and her blue eyes widened. ''But I heard from Len...''

''Len thinks that because I was helping Miku make him jealous, so that he would make a move.'' He frowned. ''And I decided to continue putting on this show because they're being total idiots and denying their attraction to each other.''

''Oh,'' Rin blinked. ''I see. I was wondering why Len looked so unhappy in class,'' she mumbled. ''They're perfect for each other, why can't they see that?''

''Because Miku is sweet, but too naive, and Len is a PMS-ing bastard,'' Gakupo glanced at Rin. ''No offence, Rin.''

''None taken,'' she laughed. ''But how would making Len jealous bring them together?''

Gakupo shrugged, hoisting his bag further up his shoulder. ''You're his sister, Rin...you know what Len can be like when he sets his sights on something he wants. Especially if he's pushed beyond his tolerance limits.''

She nodded. ''I know, but...'' she frowned. ''If you're hoping for Len to lose control and do something desperate, I worry for Miku.''

Gakupo frowned too. He didn't think of that. ''Ah, well, Miku will be fine,'' he said nonchalantly. ''After all, what's the worst thing Len can possibly do to her?''

:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:

Once again, Miku felt his eyes staring at her back. She whirled around, trying to catch him staring at her, but he was already looking elsewhere. She sighed, strangely disappointed.

Why are you so eager anyway? You're supposed to be getting over Len Kagamine, not hoping that he's sneaking glances at you.

She had been unconsciously staring at Len the whole day, only looking away when he caught her looking. He had been surrounded by girls, as usual, and it made Miku feel...envious. And a little sad.

It seemed as though Len never had any real feelings for her. That was why he could move on so fast, wasn't it?

But she could swear that she felt eyes boring into her back whenever she talked to Gakupo. Again, she glanced at the blonde, who was talking to Teto and Neru.

Neru had even set aside her beloved phone so she could talk to Len, which just showed exactly how much he was welcomed by girls. He could haveany girl he wanted, so why would he want someone like Miku?

Gakupo laughed, dragging her back into the discussion they were having with Rin, Kaito and Piko about their favourite foods. Miku forced a smile and joined in, saying that leeks were the best food on Earth, while Kaito pointed out the merits of ice-cream.

Again, she felt eyes on her back. This time, she didn't bother turning around to look - she'd never catch him staring at her, anyway.

How could she even be sure that the eyes she could feel on her back belonged to Len Kagamine? He had better things to look at.

''Hello? Earth to Miku Hatsune,'' Rin snapped her fingers in front of Miku's face, and she blinked, startled. ''I've been trying to get your attention for five whole minutes!''

''Sorry, Rin,'' Miku mumbled. ''You were talking about oranges?''

Rin sighed. ''It's about something else.'' She regarded Miku with her blue eyes, those blue eyes which looked exactly like Len's. She looked so much like her twin brother it made Miku's heart ache.

''You're coming by later, aren't you?'' she asked. ''Len asked me to pass a message. He says to go to our house directly. He has some school stuff to settle so he'll be back later than usual. Here,'' she took out a bunch of keys, dangling from an orange-shaped keychain, ''take my keys.''

Hesitantly, Miku took the keys. ''Then what about you?'' she asked Rin. Rin grinned.

''I have a set of spare keys. And even if I lose those, Len will open the gates for me - he usually doesn't sleep before I return home, in case I didlose my keys,'' she sounded a little guilty. ''That's why he's always so tired.''

''Why do you go out so much, then?'' Miku asked curiously. Rin shrugged.

''Sometimes, I'm out with Kaito. And I have a part-time job at a cafe nearby. Occasionally, I take the night shift,'' she smiled. ''Don't worry about me, Miku. Worry about your maths.''

Miku's cheeks warmed at the reminder. She had just gotten back one of their maths test, an algebra test she had taken before Len had started tutoring her. And she had scored the lowest in class, with a mark of five out of fifty.

She supposed it could be worse - she had gotten three out of fifty before, for another algebra test. Algebra really was terrible.

Again, she felt eyes on her back. Her head whipped around, and she managed to catch Len looking at her this time.

His blue eyes met hers, filled with a mixture of sadness and...a little bit of hurt. He didn't look away, so she did, quickly averting her gaze.

Why, of all emotions, hurt?

:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:

Miku reached Len's house, and she stood before the gates, wondering whether she ought to just continue walking back to her house.

She didn't know how to face Len, especially not now. She didn't know how to act around him - should she pretend that nothing had happened? Or should she make some reference to what they had done, the other night?

Sighing, she slid Rin's keys into the gate's lock, and the gates swung open. She walked past the gates, locking the gates as she entered their front yard.

Entering the house, she made her way up to Len's room, already familiar to her. Sitting on the bed, she stared around the room.

Here was where their relationship had changed - for the better or for worse, she didn't know. She had known intimacy with him like she had with no one else, and she still didn't know what to do about it.

She leant against the headboard, pulling their maths homework out of her bag. They didn't have much today, and as Miku started on the first sum she was surprised she could actually solve it without help.

Albeit slower than most of the people in class. It was still a start, though. It seemed as though Len's guidance really did help.

She bent her head, focusing on her homework, pushing thoughts of Len Kagamine out of her mind.

:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:

Miku was concentrating so intently upon her work that she didn't notice when Len had returned. It was only when she heard his voice from the doorway that she looked up from her worksheets, startled.

''How long have you been here?'' was what he had asked, his voice toneless.

''Half an hour or so?'' she replied hesitantly. He didn't respond, instead walking across the room to sit at the other end of the bed. Close enough that he could still teach, but too far to touch.

Miku felt hurt, for some reason. But she didn't let any of that hurt show on her face.

''Are you stuck on that question?'' Len tilted his head, voice still dead, blue eyes frozen over. She nodded, biting her lower lip.

''Could you explain it? Please? I've checked my working twice and I still can't find the mistake.''

''Of course I can explain it,'' he said, face devoid of expression. ''That's all I'm supposed to do, isn't it? Be a tutor.''

He started explaining the question before Miku had the chance to think about his words.

:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:

Finally, she finished all her work, in slightly under an hour. Len had been cold the whole time. Not just cool and distant, but cold. And she didn't understand why.

''I'm done,'' she mumbled, packing her things. ''So I can leave now, as you so obviously want me to.''

He glanced up at her from beneath long eyelashes. ''What if I said I didn't want you to leave?'' he asked, and for the first time since they started the study session she heard emotion in his voice. ''Would that change anything, then?''

''I don't -'' she started, but before she could complete her sentence, Len had pushed her beneath him, one of his hands locked around her wrists, over her head, so she couldn't move her arms. She gasped. ''Len!''

''Miku,'' he murmured, his free hand trailing across the bare skin of her upper arm. She couldn't help but shiver - despite how she tried to convince herself, she was still attracted to Len Kagamine. ''Are you punishing me for something I didn't do?''

''I don't understand what you mean,'' Miku gasped out, breathless. Len's eyes flicked to hers, green clashing with cerulean blue.

''Do you know how you make me feel every time I see you with Gakupo?'' he asked, those eyes smouldering with anger, and a hint of the same hurt she had seen this afternoon. ''I can't stand it - it feels like I'm being punished for a crime I didn't commit.''

''Why should you care?'' she shot back, eyes narrowing. ''You don't have any right to be angry, Len. You're not my boyfriend.''

''Is he?'' Len shot back bluntly, and Miku's eyes widened. Did he know?

''What do you think?'' she retorted. Len's eyelids lowered sensuously, his eyelashes brushing against his cheeks.

''I don't think you really like him that way, Miku,'' he breathed, leaning down so that his cool, cinnamon-scented breath washed against her cheek. ''You act differently around him, as compared to how you act around me.''

''And what makes you think that I'm attracted to you, not him?'' Miku struggled, trying to escape Len's grip, but he was stronger than her and she couldn't move an inch.

''Because you told me you liked me, remember?'' he said softly, their faces so close that their lips were mere centimetres apart.

Miku forgot what she was going to say. With bated breath, she watched as Len lowered his lips to hers, and she moaned, unable to help her reaction to the spice of his taste.

Their teeth banged and scraped, their tongues dancing together as they kissed, tasting each other's flavour and spice. Miku enjoyed the kiss, her eyelids fluttering closed, then they snapped open, and she realised she wasn't supposed to like him anymore.

She yanked her head away. ''Len, get off me,'' she warned. ''Or I'm going to bite you.''

He gazed down at her, eyes heavy-lidded. ''Bite me all you want. I think I'll like it,'' he offered, smirking. Miku scowled at him.

''Let me go!'' she yanked against his grip, but still it didn't loosen.

Len's other hand drifted towards her top, towards the buttons of her blouse. She froze. ''Len...'' she said warningly. ''Stop it.''

He ignored her, proceeding with whatever he was doing, and Miku's eyes widened in a mixture of excitement and fear. But more of fear. ''Len! I'm serious!''

Still, he ignored her, even when she started struggling again. All he did was tighten his grip on her arms. She couldn't move her body as it was pinned by his weight.

She knew what he was going to do, and she knew she wasn't going to like it. She wasn't going to like it at all.

''Len!'''
