The wind went out on it's next search, it arrived in an area that was near the countryside, it was still a city but nearer to a countryside. Over there had three of the EXO boy's living one area, but not knowing each other.

It was morning when the wind arrived and it died down slowly, waiting for the right time to appear.

It stayed near to one of the EXO boy's house, patiently waiting. And there it was the sound of the boy, Byun Baekhyun woke up with a yawn and stretched his body as he got out of bed. He was very tired from all his martial arts training since last night, Baekhyun was orginally from Busan but moved to Seoul when he was 15 to get extreme training for competitions and he had another match tomorrow with the China martial arts team. 

"Ow." He groaned in pain as he felt a sore feeling on his shoulder and massaged it with his other hand. *This is terrible.* He thought and sighed. Baekhyun got up and went to shower up, getting ready for the day.

As he went in the shower, he was humming to a familiar tune that made the wind came back to live, he opened the bathroom window while brushing his teeth as he continue to hum the tune.

Just as he finish rinsing his face the wind blew by and into his room. Baekhyun gasped out loud from the sudden burst of the wind. "What the!" He jumped slightly.

"Oh, it's just a wind." He sighed in relief and at the same time when he shrugged his shoulders and was going to take a shower. The wind blew open his closet door, making a loud banging sound.

Baekhyun gasped and jumped a bit, he ran out of his bathroom and stare at his bedroom. "Yah! Shh! The other members are still sleeping!" He hissed softly at the wind, expecting it to listen.

But the wind continued to make sounds in his room, all different types of sounds, the sound of the closet doors banging and the whoosh of the wind it made, "Yah! Stop! You're making noise!" He went over to stop it but the wind's whoosh became louder and so did the banging of the closet doors.

Just as Baekhyun was about to snapped at it, he stopped halfway and listened. At that moment he had realized that the wind wasn't making any noises, it was creating the same tune as his humming.

"My humming?" Just as it was Baekhyun had guessed the correct answer, the wind continue to made the sound. Baekhyun was beyond confused, a magical wind was creating music in his room. But he remember this tune, this was when he was small, he had heard this sound before.

This familiar tone, this beautiful lullaby he listened often before going to sleep. And sometimes he sing it to himself before he sleeps, but he forgot the lyrics for it so he only hums it.

Baekhyun was drawn back to memory lane and smiled as he joined the wind, he started to hum loudly and beautifully to the music the wind was making. And just like that the two created a magical sound that made somewhere inside Baekhyun's chest lit up.

Baekhyun gasped at the same time and turn to his chest, it was glowing bright and he lifted up his shirt, his birthmark right on top of his left chest grew bright.

His birthmark was the EXO logo and Baekhyun just stare at it, fascinated by it. "What?"

The wind made it's last tune and went out of his window, disappearing from his room. Baekhyun followed the wind to the window and watch as it flew off.

Just as it did, his birthmark stop glowing. Baekhyun now stare at it, what at first seemed to look like a hexagon birthmark now had a new addition on it. 

A three letter words. "E..XO?" He read, baffled and suspicious. He then turn back to the window, "What could this mean?"

Just as the wind had finished finding one of the other sons, it went down to another house, only a few blocks away from Baekhyun's house.

This one was already awake and ready for an adventure. It was Park Chanyeol. He had his travelling suit on, Chanyeol's family were both adventurers and Chanyeol learned from them on how to explore things outside and discovered new things.

He loves mysteries and always bound to solve them.  Right now, he's sipping onto his coffee while flipping through his notes, reading his past mysteries. He is now finding a new myst
