A/N: Hey guys! I just wanted to let you know about the mistake I made regarding Marinette's birthday. In my fanfic, she is actually fifteen turning sixteen and not seventeen turning eighteen, therefore her birthday is May 25th, 2002; not 2000. Anyways...eheh...that's about it, let's get to the chapter now.

Marinette knew she had to assemble a plan quickly. She had no idea where this merboy was, and she did not even know where to begin searching for him. I might as well start by going to the ocean, Marinette thought to herself as she rolled her eyes and smiled. She tiptoed downstairs quietly, totally forgetting about her mom. She was just about to grasp open the door handle when she heard her talking from right behind her. Marinette froze in her tracks.

"Sweetie, where are you going this time of hour? Usually you would still be in bed on a Saturday", her mom asked worriedly. Marinette had to bite her lip to prevent her from spilling the truth. "In fact", her mom paused to lower the mug she was holding, "You've been acting quite strange this morning. Are you feeling alright? Is there something you want to tell me?" Marinette was panicking on the inside. She hadn't thought about all the answers she would have to make up for her strange actions. She avoided her mom's gaze and nervously twirled her fingers. "Umm...I just wanted to go for a walk for fresh air and exercise...", she mumbled under her breath. But before her mother had the chance to reply; Marinette rushed out the door, her palms sweaty with guilty relief.

She felt awful lying to her mom like that, but then again, what would she even say? Her mom would freak out if she discovered she was part "fish". She shook her head, throwing out all the negativity and guilt bundled inside of her. She needed to concentrate on the task at hand. Go to the ocean. Find the boy. Tell him to change her back. Then, at least she would be a normal girl again. Should be simple enough, right? She stopped abruptly, unaware of how fast it took her to walk to the beach compared to last night. The waves were stretching outwards, almost touching Marinette's toes. She backed up quickly but then stopped. If she was going to do this, she would have to face her fear, and that would mean...gulp...going in the water.

She inched slowly at first, but then gave up and started walking faster and faster into the water. She could already feel the prickling sensation in her legs, feet, and torso. She was about three feet in the water. Sudden sounds of people talking and laughing snapped up to her attention. She whipped her head around to see a group of people settling down on the beach. She looked back into the deep blue of the ocean. She must not let them see her, or her tail, for that matter. She took a deep breath and squeezed her eyes shut as she dived into the ocean with a small splash.

Marinette was just below the surface when her legs were transforming into a tail. Through her shut eyes she could feel the binding of them and the cold flushes. Oddly enough, the transformation seemed to have hurt less when she was underwater. A minute passed. Marinette could no longer feel her two legs, but one powerful tail. She opened her eyes, expecting the salt of the ocean to burn them. Instead she saw normally, and perhaps even better in the salt water than she ever did on land.

She took in the scenery of the ocean. Sure, she was only a few feet underwater, but it was a still breathtaking sight. The morning sun was just peeking out and the soft rays lit up the ocean. The sand was the purest white and there were colorful corals everywhere. She watched a few angelfish swim past her, giving her quizzical looks. She realized just then that she was still holding her breath. She was underwater...she couldn't possibly be able to breathe. Her air was running out quickly, and Marinette was still trying her best to hold it in. Finally, she couldn't hold it in anymore. Please let me survive, please let me survive, please let me survive, Marinette thought fiercely.

She let go of her breath. She was breathing in short rapid breaths. Marinette was shocked. Water didn't come into her body and drowned her like how it would be for a human being. She smiled and giggled, breathing in deeply. Marinette soon found herself distracted from her mission, exploring the ocean and all its wonders. She was just swimming through the colorful corals, swirling up the sand when her thoughts came back to her. She slapped her head, dropping the beautiful cream seashell she was clutching. How?! How in the world did she get so distracted? She should be resenting every moment in the ocean but instead, found herself enjoying it.

She swam up to get a better view of the ocean. Everything seemed as it was, with nothing extraordinary about it. Where in the world would a boy who lives in the sea even live? Marinette swam in one direction but then decided to swim the other way. This went on for quite some time before she realized she circled the same rock five times. She groaned, her hands on her face. This is not happening to me... Something must've heard her then, because a strong water current tumbled right into her making her to fall flat on her stomach in the water. Marinette squealed in surprise, trying to get back up again and swim out. But the water current shaped itself to be like a powerful invisible surfboard, and Marinette was on it.

Before she had time to process what was going on, the water current burst through the water, so fast it was making Marinette's hair and tail fly backwards. The water was swirling past her with such ferocity that she was forced to shut her eyes and let the water current take her wherever it pleases.

Adrien was silently swimming around a coral. He has been out of the house for three hours now, feeling guilty about disobeying his adopted family. He stopped swimming and sighed, laying back on the coral. He thumped his fins on the sand amusingly and fiddled with his ring. He looked up towards the surface remembering what he had done. How was the girl now? Did she make it back to her house? These sorts of questions flooded his mind as he continued looking up. There was a sudden shift in the water, making Adrien's spine tingle. Hmm...that was weird..., he thought. Maybe he should be heading home right about now and the ocean was agreeing with him.

Standing up, he began swimming home, but was caught off guard when he heard someone cry, "WATCH OUT!" Adrien turned his head around to see a blur of a mermaid with shiny crimson scales flying right to him. His eyes widened in surprise and confusion, preparing to dive out of her way. The mermaid was too quick though and instead crashed into him, the impact sending them both tumbling to the sand.
