Well, this is a plan to get the King and Queen to hate Len. You can't expect it to be cute and adorable. More like repulsive and scary.
Step 1: Apply Ring
Miku examined the metal ring in Len's hand with a light blush coating her cheeks. "Oh, Len, I don't I have the same feelings for you, I'm sorry. And that is not a proper proposal ring."
The male in front of her again had a 'How blonde are you?' plastered on his face. "Miku, you do know we're faking this thing, right? And I'm pretending to marry you!"
"Oh? Then why are you holding such a pathetic ring in your hand?" She questioned while trying to hide her embarrassment.
"Because it's supposed to be a nose ring. I asked one of the villagers to cut a hole in the side. All you have to do is stick it on your nose." He explained as she handed her a wooden box. "Use this is if the ring doesn't fit on your tiny nose."
Inside the box was a sticky, brown residue. With a shriek, Miku dropped the box on the floor. "Ew! Is that some kind of peasant's glue!"
"No! It's just tree sap!" Len emphasized the word 'just'.
Hesitantly, the Princess of Pure picked up the box. "Oh." She puffed. "You should have just said so from the beginning."
Step 2: Color Hair
"Why are you painting my hair, anyway?" Miku asked curiously.
"Because we're playing a game. What kind of game, your pea-sized brain may be wondering? Well, I like to call it My Peasant Boyfriend is a Bad Influence on Me. The point of the game is to get the girlfriend's parents to hate her peasant boyfriend!" Len explained sarcastically.
The Princess pouted. "Hey! My brain is not pea sized!"
Sighing, Len continued to paint. "As I've been saying, wanna bet?"
Clasping her hands together, she put on a dreamy look. "It doesn't matter what you say! Because soon, Mamma and Papa will say that anybody would be better than an ugly, worthless peasant like you! And then I'll once again be in the warm embrace of my Prince Kaito!"
Why was it that Len hated the sound of Prince Kaito's name? It sounded like some annoying bug slamming against a lantern. "Bzzt! Prince Kaito! Bzzt! Prince Kaito!" And Miku loved this guy? Come on, he can't be that great.
For the record, Len also wasn't ugly or worthless. He swore that if he had all the necessities to be clean Miku would be swooning over him and not that bug. And he swore that he had made Miku much happier than Prince Kaito ever had.
Miku glared at herself in the mirror. "I hate it."
"Well hopefully you get your traits from your parents." The blonde replied as he put the containers of paint back into the potato sack.
"Wait! I didn't get to paint your hair yet!"
"Not now! You can later!"
Step 3: Drugs
Out of the brown sack designed for potatoes came wooden pipes and straws along with a couple bowls of pink powder. Miku found these items very interesting. She watched intensely as Len poured the contents of the bowls into the pipes.
"What is that?" She asked.
"Well it's supposed to look like tobacco but-" He was cut off.
Princess gasped. "You want me to use tobacco? Have you no heart or intelligence?"
Face palm action go! "No, this is just ground up, dried strawberries for your highness."
A red color poured into her cheeks. "N-Now that you mention it, it does smell of strawberries in here!"
"To create the image of smoking you have to blow the powder out gently- Ugh!" Len was cut off as a pink powder splat on his face.
"Eh-hehehehe… Do you have any other powders?"
It turns out Len just happened to also have apple and banana powder. There was no surprise when Miku failed the apple powder but the banana powder did work. In fact Len actually thought she was smoking. Which was weird, considering he thought of the plan.
Step 4: Show it off
The King and Queen of Pure hated when Len walked around the castle, let alone barefoot! But what were they to do? They had already taken away their daughter's first love, taking away the one who was actually living in their country would just be harsh.
But this – their daughter wearing black, torn clothing was utter madness! Her beautiful, silky, teal locks being tainted with disgusting colors of red, blue and black! Her delicate skin was pierced with a revolting piece of metal! And she was killing her fragile lungs with tobacco no less! Who could possibly be to blame for this?
Well it was none other than the poorest of the poor, the ugliest and most worthless: Len Kagamine! Not only did he have piercings in his ears but his hair was dyed green and red! Had he been forcing their daughter to wear is tattered clothing? Was he the one that told her smoking was cool and fun?
"M-Miku! What has happened to you?" The King cried.
Princess Miku of Pure rolled her eyes. "Jeez, Dad, calm down. This is cool, ya'know? Man up a bit and get in style!" She sassed and took a big breath of tobacco or banana powder.
Len then put his arm around her shoulders. "Yeah, Pops, I think you should be proud of what I've exposed your daughter to. I mean, this is just art. And that pipe? It's the best in the kingdom along with the best chiz."
A look of confusion plastered onto the Queens face. "'Chiz? Is that a bowl movement?'" She questioned.
"Nah, it's just crack."
The Queen instantly went pale. "Oh Dear Lord!" How much more of this could she possibly take?
"What? This is cool, Mom." Miku noted as she pecked Len's lips.
Before she could pull away Len held her face and licked her lips with a slobbery tongue. In disgust, The Queen of Pure instantly passed out along with The King. Unable to hold back their giggles, the two 'lovers' burst out in laughter.
