A/N: I have no explanation for this story whatsoever, except that this is the kind of thing my brain creates late at night. I apologise in advance.

(Though, I don't have too hard a time imagining Daisy trying to blackmail people, if only in a joking manner.)

'Wait, what-'

'Shhh.' Daisy put a finger to her lips for emphasis.

'I'm not sure why-'

'Shhhh!'

Luigi groaned, pushing up the back of his cap so he could rake some fingers through his hair in what he hoped was a suitably exasperated gesture. 'I don't understand why we're doing this.'

'Because it's fun,' Daisy replied. 'And trust me, I just know this recording will come in handy someday. Just try not to make any noise.' She gave an evil grin, shook the camera in his face, and then started walking.

They were in the gardens of Peach's castle. It was nighttime, very dark, and quite cold – which wasn't surprising given that it was January. Inside the castle, Mario was supposed to be having a romantic dinner with his lover, Princess Peach. The pair had been together for a few weeks now, but so far, they hadn't told anyone except for Luigi and Daisy. They claimed that they weren't yet ready to reveal to the whole kingdom that they were dating. In Luigi's opinion, it had more to do with the fact that Mario was scared stiff of how all their friends and family might react to the news.

It's ridiculous, he grumbled in his mind. Everyone already knows how much they like each other...

Abruptly, he was jolted out of his thoughts by Daisy tugging on his arm and pointing upwards. They were standing right below the castle wall. Above them was a large balcony with elegantly-carved railing made from white stone.

'That's Peach's room up there,' Daisy murmured. 'She and Mario are probably in there together. If we can climb up somehow... then I bet I can get a picture of them...'

Luigi squinted, eyeing up the distance between the balcony and the ground. He knew he could make it with a good jump, but Daisy would never be able to. Besides, the implications of her words were enough to make him want to recoil backwards as far as possible.

He turned around to find her watching him expectantly, and knew it was time to put his foot down.

'No, Daisy,' he said, in the firmest voice he could muster. 'I'm... I'm not gonna trespass on Peach's property so you can take pictures of her and Mario doing... whatever they're doing in there and use it as blackmail against them. He's my own brother!' he added in a kind of horrified whisper.

Daisy's face fell, but not for long.

'...Yeah, you're probably right,' she said thoughtfully. 'I mean, I'd never really blackmail them. I just wanted to send them the pictures, for a joke. But maybe that's a little too mean even for me.' She grinned ruefully, while Luigi let out a huge sigh of relief. He loved Daisy (no matter how much he struggled to say it out loud) but there was only so much of her weird ideas and practical jokes he could take.

'Let's go, then,' he said. 'It's freezing out here...'

He started to walk back the way they'd come, when Daisy suddenly halted his movement by grabbing his arm and pushing him backwards into the castle wall. 'Wait, what-' he managed to say before ducked her head and kissed him, cutting him off.

'I didn't want this whole expedition to be a waste of time,' she said afterwards by way of explanation, while grinning mischievously. Luigi just stared up at her in a kind of daze, his hat askew.

'...I-I don't mind,' he stuttered, after several seconds of opening and closing his mouth without any words coming out. Daisy smiled (genuinely this time) and leaned down to kiss him, and this time he wasn't too surprised to respond.

Meanwhile, on the balcony above them, Peach was leaning over the railing and adjusting her camera.

'This is so weird,' Mario muttered from behind her.

She smiled. 'Well, they were about to do it to us. It's only fair to take payback while we have the chance. Besides, this might come in handy for the next time Daisy and I have any disagreements about our kingdoms' alliance.'
