The train travelled rather slowly in Miku's perspective. She didn't want to go to sleep as it would be really hard to wake up later so she stayed up reading until they arrived at the fishing village. It was dark and just a few people got out of the train along with her. Her house was within walking distance from the station and she walked towards its direction. However, in her way she found a large mysterious tree. She placed her ear on its trunk. "She's coming," a voice whispered. Miku widened her eyes.

"Could it be referring to Luka-senpai?" she wondered. In any case that was Miku's secret. She could actually communicate with some trees, but she had never talked about that with anyone rather than her father.

In the morning, when she had had some sleep her father called in the man he had talked to her about. "This is Hiyama Kiyoteru," a tall man with glasses showed up in front of Miku. His smile was somehow mysterious and Miku couldn't help but wonder where he was going to take her.

"Nice to meet you," she bowed.

She had already arrived in her home village and met with her new "mentor" but she sensed that something really unexpected was about to happen.

"Kiyoteru-sensei, where are we going?" she asked as they were together in the beach.

"Just follow me," he smiled. "There is something you must know."

"What do you mean?" Miku asked surprised. However the man didn't answer. Instead he guided her towards a small boat. They both got in and he rode it until they reached the ancient ruins. It was basically a ruined flooded temple in the middle of the beach. It seemed to have Greek influences. Miku stepped out of the boat. The water reached her hips but it was extremely translucent. "What is this place?" she asked.

"This is where you come from… Unfortunately it was destroyed some years ago…" he explained.

"So it wasn't a ruin…" Miku said disappointed. "But… I don't come from here…" she said.

"In a sense no, in a sense yes… There is a reason your father called you here so urgently, I did some research," Kiyoteru-sensei began.

"Wh… what research?" Miku asked hesitantly.

"Sit here," he suggested and she sat next to him in one of the rocks that had been used to build the temple. "Do you know that fairies used to live here?" he asked.

"So… this temple was theirs?" Miku deduced.

"Exactly, thought it wasn't a temple," Kiyoteru-sensei replied. "This is where you were actually born,"

"Ugh, um, how can that be?" Miku shuddered.

"Sometimes, fairies place changelings in the place of a human baby for unknown reasons," he started.

"Are you saying I'm a changeling…?" Miku widened her eyes.

"That's probably true," he stated. "I know this might be a bit sudden but you probably needed to know that you were actually…"

"A fairy?" Miku asked.

"No, fairies wouldn't place a child of their own race as a changeling…" he said with a thoughtful expression.

"So what am I?" Miku asked with a worried.

"A nymph from the woods…" Kiyoteru-sensei replied bodly.

"W- wait… How can you know that in the first place?" Miku asked troubled.

"Well, that's what I deduced from the information your father gave me. Plus, you can communicate with trees, can't you?" he smiled. Miku looked away.

"It's true… I can…" she admitted with a guilty expression.

"There's no need to be sad. I'm sure your father won't change his opinion about you due to that," he patted her head.

"Yes, but how about… the real child?" she queried with a sorrowful expression.

"It was probably… killed…" he answered with the same expression.

At night, they set up a small tent because as her father said Kiyoteru-sensei had to do some type of research and Miku was going to help. She had gone to sleep really late last night though and now she wasn't able to fall asleep. After realizing that she wasn't going to sleep no matter what, she got up and sat in one of the rocks. She moved the legs back and forward, splashing in the water. However, something broke the silence. She quickly took her legs out of the water and looked around her. Unexpectedly, something grabbed her from behind.

"Luka-senpai?" she said when she had the opportunity to look at her.

"I came," Luka replied with a dull expression. Miku's face brightened.

"Thank you!" she exclaimed and threw herself in her arms causing Luka to fall on the water with Miku on top.

"Now you've done it," Luka answered. Miku laughed.

"It's okay, you already were soaked to begin with," she smiled.

"But you were not," Luka looked away. "You'll catch a cold or something,"

"It's fine! I already got wet when I hugged you!" Miku exclaimed with a grin.

"That sounds weird, you know…" Luka mumbled.

"Eh?! I didn't mean it like that!" Miku said in panic. Luka giggled and hugged Miku back.

"I just came because I missed you…" she whispered.

They walked in the beach for hours, holding hands. Luka smiled at Miku warmly, like she had never done before. "I'm so glad we have become friends!" Miku exclaimed.

"Wha…?!" Luka blurted.

"What's wrong, Luka-chan?" Miku asked confused.

"I- I- thought!" Luka tried to explain as she blushed.

"Hm?"

"I thought we were more than just friends!" Luka said angrily. Miku put a finger in her jaw and gave her a thoughtful expression. Slowly though, upon realizing what Luka had just said she began blushing furiously. "What? Miku, answer me!" Luka said concerned.

"Um, what did you say Luka-chan? Did you just say that…?" Miku didn't complete her phrase and looked away nervously.

"Yes, yes! I did!" Luka confessed. "So?"

"Um, okay… we're… more than just friends…" Miku admitted as she looked away.

"Look at me!" Luka demanded.

"But…!" Miku fought but it was too late since Luka turned her head towards herself.

"I like you, Miku… I've liked you for a long time…" Luka said a bit embarrassed.

"I like you too, but…but…"

"Close your eyes," Luka whispered as she leaned closer.

"Geez! Luka-chan, you are you to fast!" Miku exclaimed as she pushed her away. Luka looked at her confused for some seconds and then sighed.

"You think so?" she asked.

"Yes!" Miku scolded her.

"O…okay, I'll wait then," Luka said with a resentful expression. Miku smiled and gave her a kiss on the cheek which caused Luka to cheer up quickly.

"Ah, Luka-chan… I forgot that I have to go to sleep now…" Miku said troubled.

"And what am I going to do in the meanwhile?" Luka asked troubled.

"Now that I think of it… I don't have the least idea…" Miku admitted.

"Perfect," Luka replied with a sarcastic tone. "Geez, it's okay. Go to sleep or you'll be reprimanded tomorrow!" she pushed Miku towards the tent.

"Um, but-" Miku began.

"I'll be okay," Luka interrupted her.

"If you say so…" Miku answered thoughtfully. "Good night then," she smiled.

After that Miku would get to see Luka every night after her expeditions until one night, she didn't show up. Miku sat in the beach. There was some grass growing on the sand. She sighed. Luka was so late. She would have normally been here. Of course she could try calling her and that's what she did but she got no answer, whatsoever. She dropped her phone in disappointment, but then suddenly something came to the surface. It was a mermaid. Miku widened her eyes. A giant wave came towards her and pulled her to the depths of the sea.

Later, during the morning, Miku had disappeared too.

"Huh? Where is Miku-chan?" Kiyoteru-sensei thought and looked for her all around the village. However, when he returned to the scene of her disappearance, he noticed some mermaid scales lying on the beach.

"She was taken by the mermaids?" he asked himself. "They only do this when someone gets romantically involved with a mermaid, making her unable to go to the sea…" he clarified in his mind. "Was Miku-chan involved with a mermaid?"

Miku didn't die though because she was a nymph and as she discovered she had the power to live anywhere as long as there was wood to keep her alive. Luckily she ended up somewhere near a ship that had sunk in ancient times. There, she waited for Luka patiently to come and save her as she didn't know how to go back to the surface.
