A bit after their debut promotions, NCT U was told that they would be moving into a new dorm. Everyone was told to pack up and when they were done, to go to the dorm. They were each given a key. 

Mahina was pretty excited. She hadn't slept in an actual dorm in years. She said bye the the other members and ran to her alley. She had a backpack that she kept all of her stuff in. She threw her few pairs of clothes in it and grabbed her guitar. She slung her backpack on and picked up her guitar, with her notebook. 

She walked back towards the entrance of the alley. Mahina looked back at the alley, her ratty mattress and scraps were all that remained. Even though she never had the most pleasant experience there, she still felt nostalgic leaving it behind.

She eventually walked away, not looking back.

Mahina arrived to the address that she'd been told. It was a nice cozy place from the outside. She slid her key into the key hole and turned it. The door opened without a hitch. She stepped in and called, "Hello?"

Silence. 

Mahina was the first one to arrive. She walked into the living room and flopped on the couch, putting her backpack down. She eventually fell asleep laying on the couch. Next to enter about an hour later was Taeyong who smiled softly at her. He sat on a chair and waited for other members to arrive at the dorm. As the others arrived they let Mahina sleep. 

"Yah- Mahina. Wake up you coconut." Mark said.

Jaehyun raised an eyebrow at the weird comment. But, didn't say anything. 

Mahina sat up and looked at the rest blearily. "Oh hi." She muttered. 

She saw the others brought 1 or 2 suitcases with them. 

"Ooh! Let's exchange phone numbers." Doyoung exclaimed. All the boys nodded while Mahina sat there a bit awkwardly. "Mahina can I have yours?"

"I-uh don't have a phone?" It came out more like a question.

"Woah. Seriously?! Where have your parents been all your life." Doyoung said teasingly.

Immediately Mahina's face grew sour and she glared at Doyoung. "Shut it." She said coldly. Her face grew extremely guarded. The members recognized this look, it was when she first joined SM and didn't trust anyone. Whatever respect and trust she gained from them was immediately thrown out the window. Mahina never talked much about her past. But the SM Rookies knew it had to be something bad to make her the way she was. 

She grabbed her backpack and guitar and stormed into a random room. It had a bunk bed and a single bed. Mahina climbed on the top bunk. She looked out the window. It was a nice day outside, a perfect day for a performance. Mahina opened her backpack and pulled out her hat and mask. She climbed out the window with her guitar and ran to a random street. 

She strummed her guitar and started playing. Then she started singing. Her voice flowing through the crowd. "Woah look-" "Isn't that Mystery-" "She's so good-"

All of a sudden Mahina saw a figure start to dance along to her song. Her eyes widened. It was Jisung. He didn't know about Mystery but here he was. She kept singing not to attract suspicion from the crowd or Jisung. When she finished the song she bowed and gestured to Jisung who looked surprised before bowing slightly as well. The crowd clapped wildly and Mahina picked up her guitar.

"Your pretty good." Jisung said to her.

"Thanks. Your pretty good at dancing, but should try something different from what you do in the studio." Mahina's voice had a teasing tone.

Jisung gasped, "Mahina?" He asked quietly.

"That's me." She said tipping her hat up a bit revealing her discolored eye to Jisung before putting it back.

"I thought you were moving into your dorm."

"Oh... Doyoung said something he shouldn't have. I got mad and left. It was the perfect day for a performance, so I came to sing. What are you doing here?"

"Oh. I don't have to go to the entertainment for a while. When I heard the music I couldn't help myself." He laughed embarrassed. 

"Sounds like you." She muttered. "Me more careful people might notice you."

"They could notice you." Jisung countered.

"Nah, They can't even see my face with this get-up." She gestured to the hat and mask. "As a loyal fan do you want a picture." She said half jokingly. 

"Sure!" Jisung exclaimed getting his phone out. 

With Mahina's face concealed they took a picture on Jisung's phone as Jisung and Mystery. 

"Well I'll head back to the dorm now. Taeyong is probably going full Mother Hen mode right now." Mahina sighed.

"Okay! Bye Mahina!" Shouted Jisung running off.

"Aish that kid." Mahina muttered shaking her head. She grabbed her guitar and started walking back to the dorm. 

Mahina went to the window where she jumped out, and saw it was still open. She hoisted herself up and climbed back through. "AHH INTRUDER!" Someone screamed. And a pillow was thrown in Mahina's face. Mahina grabbed it after it hit the floor and brushed off invisible dust. She pulled down her mask and stared at the offending attacker. Taeyong.

"Mother Hen. I'm not a ding dang intruder." She said scowling at Taeyong.

She climbed up on the bed she threw her stuff on, and brought her guitar up. She sat there playing chords, as Taeyong recovered. "Where were you?" He demanded, turning into full Mother Hen mode.

"Out." Mahina responded vaguely. 

The door creaked open, and Mark peeked through. "Taeyong was there an intruder? We heard you screaming."

"Oh Mahina just scared me."

Mark looked up at the top of the bunk bed to see Mahina waving down to him.

"Oh your back." He said. 

"Mhmn." Was the response he got.

"What was going on earlier?" Taeyong shot Mark a warning look as Mahina stopped her chord.

"Nothing. Just brought up something I don't want to talk about." Mahina muttered. She looked at Taeyong and Mark musing to herself whether she should tell any more people about her past. "Close the door and come in. I'll tell you a bit about it."

Their eyes widened and Mark slipped in and shut the door. He climbed up to the top bunk and sat next to Mahina, whereas Taeyong sat on the single bed looking up at the two.

"Now you better not tell anyone this okay? And you better not look at me different because of it." The two nodded in agreement. "So I'm from Hawaii, it was pretty nice. One day my parents and I  took a vacation to Seoul. Or well we were going to. They never made it that far. Some people took control of the plane, and crashed it into the water. Unluckily or luckily I am the only survivor of that flight." She traced the scar over her blind eye. "That's how I became blind in this eye." She turned back to Taeyong and Mark. "That's how I got to Seoul. That was about 7 years ago. Since then, I've lived in Seoul. That's where I met you guys."

Mahina looked up to see both Mark and Taeyong staring at her. "That's all I'm going to tell you guys right now." She said firmly. All of a sudden the door opened. Cue Doyoung and Jaehyun falling in. Mahina only sighed. "You people are eavesdroppers you know that? I guess you two know know. Great." 

"Sorry." They both muttered. 

Mahina waved it off. It's not like she could do anything about it now. Just four more people knew her secrets. "Let's go eat something." Mahina said. She climbed down and left the room leaving the four boys with each other. 

They all looked at each other then left.
