Sungmin and Jaemin sat together and ate dumplings in silence.

Sungmin was reading a small book while she ate, but Jaemin just couldn't take his eyes off of her. After a while, she finally noticed that he was staring.

"What's up dad?"

Jaemin only sighed before responding.

"How did you become a queen so fast...?"

"H-Huh?!"

She squealed, dropping her chopsticks.

"Before we lost the turtle, you were my little princess that still called me 'Daddy'. Now that you've returned, you've grown up to become such a queen that just refers to me as 'Dad' now..."

Jaemin dramatically explained.

"Dad... Just because I switched up what I call you, doesn't mean that I love you any less..."

"I know... It's just that you grew up so fast you know? I didn't get enough time to cherish you while you were still six, and now you're already fourteen! What'll your mother say when she finds out...?"

"I'm sure mom will understand. I had to grow up in order to help Chanyeol-oppa and BamBam-oppa"

"And for that, I'm so proud of you princess~. Oh wait. I guess I should stop calling you that now..."

"Actually, I like princess more than queen. I don't mind if you keep calling me that"

"Oh that's a relief! I actually think princess suits you a lot better~. Oh wait! How did you manage to destroy the earrings that were controlling Boy Story?"

"Oh yeah! I forgot to show you!"

Sungmin immediately stood up and extended her hand out. Immediately, her Keyblade materialized in her hand.

"I finally have a Keyblade too dad, just like you~!"

"No way~! I knew that you would get one! This is so awesome~!"

"It's thanks to you dad~. You made that toy Keyblade for me years ago~. On top of that, you bequeathed me your Keyblade when you let me play with it~"

Jaemin immediately remembered what Sungmin was talking about.

When Sungmin was really little, Jaemin crafted a small wooden Keyblade for her to play with.

He noticed that she was very curious and interested in his Keyblade, and would often play with it.

It was then that Jaemin chose Sungmin as his successor. He knew that if anything went awry and he couldn't be there, that she would be able to defend herself.

He not only made it in hopes that she would inherit the power to wield a Keyblade of her own, but also in hopes that she could have fun with a toy Keyblade that fit her size and that wasn't too heavy, despite it not having any powers besides physical attacks.

"I always hoped that I would have a Keyblade of my own one day. Now I can finally work my way up to become your true successor~"

"I look forward to it~. But don't let that responsibility stress you out. I want you to have fun while using it to protect others"

"Don't worry, I won't. And besides, I'm not alone. You and Key-oppa can wield a Keyblade too, so I won't be the only one~"

"I heard my name"

Key entered the room and approached the two, with a smile plastered on his face.

"You seem happier than usual hyung. What's up?"

"It's nice having other Keyblade wielders to talk to and hang out with. I having something for you Jaemin"

"For me???"

Key nodded and extended his hand out.

Immediately, a Keyblade that wasn't his own materialized in his hand, closely resembling his.

"Is that an Ultima Weapon??!"

"It is. I synthesized it for you, so that we could both have one. I call mine Ultima Weapon D, since I see and act through the darkness. But I'm thinking you should call yours Ultima Weapon H, because you act with your heart"

He smiled, handing Jaemin his new Keyblade.

"You're really giving it to me hyung...? I know that the materials used to make it weren't easy to come by... You shouldn't waste it on me..."

"The materials weren't easy to obtain, which is all the more reason I'm giving it to you. You're worth every minute I spent looking for the materials. Giving you this Keyblade would never be a waste. And besides, it's not everyday I get to do something for a fellow Keyblade wielder"

"But..."

"Use it to your advantage"

Before Jaemin could protest any further, Key quickly left the room, nearly bumping into the wall in the process.

"Where are you trying to get to oppa?"

Sungmin asked.

"Back to my shared room with my members..."

He sighed as he held on to the wall.

"We'll help you hyung~"

Jaemin cheered, dematerializing his new Keyblade.

"Thank you..."

Sungmin and Jaemin held each of his hands and slowly led him down the hall of the ship.

"So hyung, how does your sight work, in more detail?"

"Well, it's a bit complicated. With inanimate objects that don't produce vibrations or frequencies on their own, like walls, I can't see at all. With those objects, I'll usually end up accidentally bumping into them. When it comes to regular people like you two, I can see you because of the vibrations and frequencies that your heartbeats produce, or by other sounds you may make. When I'm only able to see you based off of your heartbeats, the images I see of you pulsate based on the speed of the beats"

"I see. So if our hearts stopped beating, you wouldn't be able to see us anymore"

Sungmin hypothesized.

"That's exactly right. Also, the images I see of you with those beats kind of flicker. The slower your hearts beat, the harder it becomes to see you because the flickers aren't as present. With normal heartbeats, I can see you as the flickers come and go within every half second. But the faster your hearts beat, the more I can see you as the image of you flickers with immense speed. Usually, I associate those images with the feeling that someone is about to die"

"That makes a lot more sense. It must be very hard for you to operate like that hyung"

"It's a challenge at times, being in almost complete darkness all the time. But I've grown used to it. And besides, it's not like I don't know what you all look like. I can see your features just fine"

"That's a relief... Oh wait. What about Jonghyun-oppa?"

"Oh yeah. When it comes to him now that he's an actual ghost, I can see him as if I wasn't blind at all. I don't need any vibrations or frequencies to see him now. His image is clear and still, without any flickers. And that makes me happy"

"So, he's like your light within your darkness"

Jaemin mumbled.

"Don't get me wrong, all of you are the light within this darkness. But, I guess you could say that he's the light that shines the brightest for me. Just seeing his smile makes that light even brighter for me"

Key smiled, looking straight ahead.

Jaemin and Sungmin became a bit sad from his explanation, but they were happy to see how at peace he was with his condition.

"Keeeeey~?"

Jonghyun suddenly called out for him, floating out of one of the rooms.

Key immediately stopped in his tracks, only smiling at the sight of him.

"I'm here hyung. We were looking for you and the others"

"There you are~. I see that you got some help to find us~"

"I did. Thank you guys for helping me"

"Of course hyung~"

"It was no biggie~"

Sungmin and Jaemin smiled brightly at the two.

Jonghyun and Key then left them to join their other members, leaving Sungmin and Jaemin to return to their dumplings.

"Is there any way that we can help him dad?"

"Hoseok-hyung's Golden Fleece might be able to help, but I think hyung would've gone to him already if he wanted to see normally"

"I see. He might not want to change at all. So we shouldn't bother him with it right?"

"Exactly. And besides, we Keyblade wielders live by a certain motto, and he seems to be using it more literally than me"

"And what's that dad?"

Sungmin asked, bringing a smile to her father's face.

"May your heart be your guiding key"
