Summary: Dahlia Yume had a horrible life. She finally escaped the hell she was living in, and fell into the hands of Trafalgar Law and the Heart Pirates. Unexpected events will twist and turn the Heart Pirates' captain inside out. Is it love at first sight or a disaster waiting to happen? (Inspired by the song from the Disney movie Hercules- I Won't Say I'm In Love)

Prologue

Dahlia Yume is one of the most successful assassins known across both the Grand Line and the New World. She is also the only person in existence to have an artificial devil's fruit ability. The fruit was a result of an experiment performed by Dr. Vegapunk, and Yume was forced to be a guinea pig for this experiment. The name of the artificial devil's fruit was the Mizu Mizu no mi. It gave her the ability to become and manipulate the element of water. Dr. Vegapunk's creation had turned an innocent girl into the most lethal person in the world.

Yume was only eight years old when she had been abducted, forced into slavery, and forced to be a test subject for science. Her porcelain skin wasn't too dark or light, but it had many scars on it. The biggest scar on the assassin was the one going down her spine. It began from the center of her shoulder blades and ended right above the dimples at the bottom of her spine.

Every scar was originally a deep gash caused by her captor, who made her life a living hell from the moment he stole her until her eighteenth birthday. Yume's birthday is on July 2nd, and every year she is getting closer to taking her own life. Ten years of her life were taken away by the monster who kidnapped her. This man was feared by most, but was loved by others. Despite his popularity, Yume only knew him as a monster.

July 2nd. The day when Dahlia Yume's life was presumed over, but it was also the day for the young woman to escape her prison.

The moonlight shines through the window into the room that Yume is in. She is currently handcuffed on the bed of her captor. Next to her is the beast himself, and she had to stop herself from strangling the bastard right then and there. The assassin had been planning her escape for the past three years, and today is the day to execute it.

Yume quietly slips out of the massive bed without waking the sleeping man, and sneaks the key to her cuffs out of his secret drawer, under the bed. In an instant, the restraints are off and before her captor can take another breath...she is gone. Out the window, through the massive garden, and through the sleeping town that is resting at the bottom of a massive hill from his home.

The assassin tries to hide in the shadows as no one is allowed outside after 10:00pm. She uses her ability to slip into the sewers, rushing out of the smelly pipes and straight into the ocean. By the time anyone notices she is gone, Yume has resurfaced on Grove 42 of Sabaody Archipelago. She is starving and fatigued beyond belief, but she manages to move herself a couple of steps before collapsing in front of the infamous yellow submarine.

Before losing consciousness, Yume hears a faint masculine voice calling out to her: "Oi! Are you alright? I'm going to help you. I'm a doctor."

Beep...Beep...Beep...

The sounds from the heart monitor are the only signs that Yume is still alive. She slowly opens her bright purple eyes to see a tall man in a lab coat. He has navy blue hair, golden yellow eyes, and numerous tattoos that are obviously hidden.

"Ah, you're awake. Do you feel any dizziness or nausea?" Her mysterious savior/doctor asks, grabbing a small flashlight and waving it in front of her eyes to check her sight. "I had to give you an IV since it looked like you haven't eaten properly in months, possibly years. You were also dehydrated, but I couldn't give you any water until you're awake."

"Uh...w-who are you?" Yume spoke softly, her voice raspy from her dehydration.

The doctor chuckles a bit and sits on a stool next to the infirmary bed the assassin is currently occupying.

"Trafalgar Law. I'm the captain of the Heart Pirates and of the submarine you're in," His eyes lingered longer than necessary on the woman's perfect figure despite the lack of nutrition. "What's your name?"

"Yume...Dahlia Yume," She replies softly and fails to hide the light tint of pink across her cheeks. "Can I have some water?"

Law nods before standing up, leaving the room only to return with a bottle of water. He didn't expect Yume to open the bottle and absorb the water through her fingertip.

How in the world did she do that? I've never heard of a water based devil's fruit before.

The captain tilts his head and studies the woman, intrigued as to how that little bit of water seemed make her look healthier. He takes the opportunity to look closely at her features; despite her short height, Yume has the body of a goddess, luscious curly black hair that fall down to her shoulders, big purple eyes that shine brightly, large breasts, perfectly round buttocks followed by the most gorgeous set of legs the doctor had ever laid eyes on.

Law is speechless by her radiance which has never happened to him since he's never been attracted to women before. However, Yume is different; she catches his full undivided attention without even trying.

"Yume was it? Are you the assassin known as the Water Demon?"

"Yeah I am...not like I wanted to be," Yume sighs, looking up to the swordsman. "Why do you want to know?"

"Would you like to join my pirate crew?"

The assassin is frozen in place by that question. She had been waiting for that question since she's been forced to assassinate numerous people. Yume nods, and Law grins widely at her answer, offering his hand to her so he can help her up.

"Wonderful." The swordsman says softly with a slight smirk.

"Really?" Yume asks shyly as she gently takes his hand, and slowly stands up, "Why say that?"

"You're the first woman I've asked to join, and you're incredibly strong. I like that."

The assassin remains silent hearing this and can't hide her blushing face.

Jeez...why did he have to be so attractive?! Ugh! I didn't plan on falling for anyone...

Her thoughts are interrupted by the sound of Law's voice.

"Oi. Did you hear me?"

"No, I'm sorry. I kinda zoned out..."

"I said since there isn't any more room in the crew's dormitory, you'll have to stay with me in my bed...it's big so we'll both fit."

D-Did I hear him correctly?!

Yume just nods as her face turns bright red; mostly with embarrassment, but other than that...the thought of being in in the same bed as the man who just saved her life is making her nervous.
