"Tell me again why I hate this so much!!!" Jein yells out loud. All of them struggle and fight the upcoming heavy flow of water from nowhere.

"Because it's wet and deadly!!?" Joon gives him some response. They struggle to float themselves on the surface.

"Don't tell me you can't swim, Wolf!" Yoon yells at Justin who looks struggling amid this flood.

"I can! But not in this worst condition ever!" Justin says. Even Twix agrees. This looks almost like they were trapped in a can and someone just rolled in the tap water and carelessly drowns them.

"Look! The keyhole almost disappear!" yells Byul. They look at the door. The keyhole almost submerges into the flood.

"Relax! I got this!" says Cygnus. From early on, he's the only one who stays calm and didn't look like a struggle at all. He dives into the water, looking for the keyhole. He notices that only one keyhole exists on the surface of the door. That must be the real one. He slips his dog tag into the slot and slowly (well of course slowly, water makes every motion slow) twist it. The door opens and all of them are sucked into the next room.

The next room got a floor with a hole, strain the water away. They were washed away by it and lay down flat like veggies inside the strain basket. Coughing and gasping fulfill the room. All of them felt exhausted after floating and almost drowning in the water.

"And someone said it's fun to go surfing!" says Yoon between his breath.

"Not in the mood for surfing anymore.." says Justin. That flood kills his spirit now. He reaches his hand towards Twix. They help each other stand up before helping the others.

"Why Cygnus doesn't look affected at all?" asks Jein. The small boy just smiles sheepishly.

"He got a diver license. And he is petite, so he can float himself well.. ouch!" Sun rubs his shoulder. He just got a smack from Cygnus.

"I ain't small, okay! Hmph!" he turns his head away. They laugh in unison. Look how cute he is with his pouty mouth.

"Okay, let's continue the journey," says Joon. He looks at the map.

"Oh no, bad news!" some part of the map has just washed away with water, making it almost disappear from the note. Joon lifts his notebook and water drips from it.

"What now?" asks Sun. Things look impossible right now. They didn't have any clue about this place anymore. All the riddles that Joon writes down in the diary are gone by now.

"Never mind, just follow Joon's instinct," says Jein, holding his hand. Joon looks at him with wide eyes.

"Baby, don't you think you just put me under deep pressure right now?" he whispers to him. Jein smiles and ruffles his wet hair.

"Don't doubt yourself, Joon. I know you can remember at least some part of it. You are a genius! I put my faith in you.." says Jein. They look at him. All of them.

"But I almost killed you guys!"

"Accidents do happen, Joon. Even in the most perfect circumstances. Just believe in yourself," says Sun, patting his shoulder lightly.

Now they just count on him. One, because he has been here before. And two, because right now all they need to do is to trust each other. Even with a small bit of information.

"We should trust each other by now. Not because we don't have a choice. But trust is the most important right now in this circumstance. So, we trust your judgment and feel free to ask our opinion," says Yoon.

"Yeah, furthermore comrades should trust each other! That's the Black Wolf spirit!" Justin looks so full of comradeship spirit. All of them somehow agree with him.

"Fine.."

"So, what are we waiting for? Show us the way, leader!" says Sun. Joon smiles, and leads them away, with Jein holding his hand tight.

"I'll always hold you, no matter what.." he says, looking at Joon and smiling.

***

"What the.." Yoon couldn't contain his feeling right now. They were standing right in front of what Cygnus called Obstacle Part One.

It looks like an empty hallway and Sun almost went past it when suddenly a set of swinging blades hung out of nowhere, making him jump back out of scared.

Now those blades didn't stop swinging. They move so violently, one mishap could cost someone's life in an instant.

Joon watches the blade. Last time he didn't encounter this obstacle. But according to his late father, the Maze City got a lot of entrances. And every entrance got its obstacle until it connect to the main entrance to the exact location.

But some paths will overlap with each other. So, it might be possible for them to encounter the same obstacle that he ever met before.

"It's swinging in some kind of...motion. Like.. a rhythm.." says Joon.

"They didn't come out all at once at the same time. Some even went out late, some came out first.." says Sun. Now all of them began to study the motion.

"Every blade got ticker time. They poke out at the same speed at certain times," says Jein.

"The question is, what is the span time from each blade?" asks Cygnus.

Byul and Yoon look at the swinging blade. Unconsciously, they tap their feet, reading the rhythm of the swinging movement. They slowly look at each other. And reads mind.

"It's not by per second. It's a movement. More like steps in.."

"Martial art basic.." both Yoon and Byul answer at the same time. They look at them meticulously.

"But how?" asks Twix.

Yoon put himself in a fighting position. He began with the first step of the Blood Crescent Moon technic then continues with the next step until the last one. Joon studies his movement from the side to look at the similarity between the movement and the timing of the poking blade.

"Almost close. But you missed certain places.." he says.

"Let's check the next one.." says Yoon. He let Byul take over. Just like Yoon, she began with the first steps of the Black Swan technic and continues the rest until finished.

"Almost close, too... but missed in certain spot.." says Joon. He frowns for a while. Suddenly, he got an idea.

"How about you guys combine those technics all together?" Byul and Yoon took their position. They began with the first step until the last one. Joon is in shock. They move so well and the movement matches the motion as well.

"So, it's a combination of the Black Swan technic with the Blood Moon Crescent technic!" says Joon.

Everyone claps their hand, celebrating the discovery together.

"So, we need to cross over the obstacle and stop those swinging blades so everyone can pass by," says Yoon to Byul.

"Okay, let's do this!" she says. Both of them standing in front of the obstacle.

"Wait! Yoon, you need to start on the right side. Because that's your first step in Blood Moon Crescent. Byul, you take the left side.." Joon arranges them according to the movement just now.

"Ready?" they take a position. They look at each other and nod.

"Go!" with that, they go into the obstacle together, using each other's technic. When they move, unconsciously they match so well, even the combination makes them mold each other's bodies. They are some parts when they need to help each other and they did that. In one certain spot, Byul can't lift her body, but Yoon manages to drag her in the slow swift motion of Blood Crescent Moon. Their back meets in the middle of the obstacle and forms a nice twirl, entwining each other's fingers and swiftly tiptoeing across the room.

Finally, they reach the other side without a single scratch. Yoon finds a keyhole and pulls Byul onto his side so she can slip the dog tag inside the keyhole. They squeeze in together as the spot on their feet only provides space for only one person. Byul hugs Yoon tight tries to balance herself and slips the dog tag. Then she twisted it, opens the door to the next level, and all the blades were gone by good.

"It works!" Twix says happily. All of them jump for joy. Byul and Yoon still hugging each other.

"Okay, the coast is clear. Let's move to the next level.." says Jein. They walk across the hallway.

"Are you guys coming or not?" asks Twix. Byul and Yoon look at him.

"You will get plenty of time to be lovey-dovey if we escape from here later.." says Jein. Both of them pull away and stood there, blushing. They smirk at them and pass by to the next room. Yoon looks at Byul with a smile and whispers to her ears.

"I love you.." makes her blush all over. Yoon quickly ran towards them and joined the crowd. Byul smiles for a while.

But later, her smiles fade away. She felt sad all of a sudden.

"I love you too, Yoon.." she whispers to herself. Knowing what will happen soon, she can only enjoy this moment while it lasts.
