Sunmi drove them to the address that Minyoung had sent. Their location had been the farthest from C’s house so she expected them to arrive later than everyone. The sun had already set but they had not reached their destination yet.

“They haven't called us since we left. I’m getting hurt now.” Kwangsoo complained as he looked at his phone.

“Do you want to go home?” Yeonseok asked him.

“Oppa, fighting!” Sunmi tried to cheer him up.

“There’s less and less reason to share everything now.” Kwangsoo told them.

“Well, we never know. They could be stuck in a deadly situation right now.” Sunmi hypothesized, not knowing how true her words were.

-- Place presumed to be C’s House --

Sunmi, Kwangsoo, and Yeonseok finally arrived at what the others said was C’s house.

“This looks like a warehouse.” Yeonseok observed.

“This is C’s house?” Kwangsoo asked.

“I guess so. This is the right address according to my GPS.” Sunmi answered.

“This is crazy.” Kwangsoo whispered as they got out of the car.

“What is this?” Yeonseok asked as they saw the giant symbol in front of the entrance. The three looked at each other before going in. There, they saw an open door.

“Is it this way?” Kwangsoo asked as they stood at the entrance. There, they saw three pairs of boots: blue, yellow, and purple.

“What is this? We have to wear rain boots? I wonder what this is.” Kwangsoo questioned.

“I think you can only step on these. With the yellow boots, only step on the yellows.” Sunmi shared.

“Wait, why can’t we just go?” Kwangsoo asked and tried to step randomly into the room. He was soon pelted with water balloons. Yeonseok and Sunmi laughed at him.

“Oppa, are you okay?” Sunmi asked.

“I’m sorry. I’m sorry I… I apologize...” Kwangsoo couldn’t stop apologizing. 

“So that happens.” Yeonseok stated.

“I was mistaken, please forgive me!” Kwangsoo called out. Soon, they could hear the voices of the others on the other side of the wall.

“Kwangsoo!” They called out.

“Hyung!” Kwangsoo replied.

“Yeonseok! Sunmi!” They could hear Jaesuk calling out.

“We just got here!” Kwangsoo let them know.

“Where are you?” Jaesuk and Jongmin asked them.

“We’re about to go in.” Kwangsoo mentioned.

“At the entrance!” Yeonseok supplied.

“Is Sunmi with you? Why can’t I hear her?” Jaesuk mentioned.

“Oppa, we got stuck in traffic!” Sunmi called out to which everyone laughed.

“Okay, let’s talk about that later.  Hurry on in!” Jaesuk told them.

“I just got hit by the water balloon!” Kwangsoo reported.

“Why? What” Jaesuk asked.

“What are you doing?” Jongmin added.

“Why did you get hit by a water balloon?” Jaesuk asked again.

“Ah, so that’s where the other door led to.” Sunmi whispered to herself.

“Oppa, I think we’re on a different path than you guys!” Sunmi called out.

“What if your trap only stops when we escape?” Jongmin asked them. There was a commotion on the other side of the wall and Yeonseok and Kwangsoo were getting ready to go through the course. 

Sunmi studied the path. The blue and yellow footprints were intersecting with each other which made her think a pair was needed. Although the purple ones looked like they were meant for one person, they were harder because a lot of the purple prints were on the wall. There were bars that someone could grab on to so Sunmi guessed that she needed to use those to reach those footprints on the walls.

“What are you doing right now?” Jaesuk asked them and at that time, Yeonseok tried the course out, only to get pelted by water balloons a few steps in.

“Oh man, what the.” He cried out and hurriedly made his way to the other side, only to still get pelted by water balloons. Sunmi and Kwangsoo looked on.

“What in the world is… Why doesn’t it stop? What is this?” Yeonseok complained. He tried to open the door there but it was of no use.

“Oppa, I think the footprints have some sort of sensor and you need to be able to step on each and every one of them so you don’t get pelted when you reach the other side and so that the door opens.” Sunmi explained to Kwangsoo.

“Hyung! Come back!” Kwangsool called out to him and Yeonseok ran back to the other side as quickly as he could.

“We have to get out. What are you guys doing?” Jaesuk called out to them.

“Let me try out my theory. I already envisioned the path I need to take to hit all the purple ones. If this works, I think you guys need to go together.” Sunmi asked as she readied herself to start. She made sure her hands were dry before she hopped onto the first mark with one leg. 

She then started to brace herself and launched herself at the bar, pulling her body up and doing the splits in mid-air to hit the two marks on each side of the wall. She then carefully did a handstand on the bar and landed as gently as she could on the set of marks that were in front of the bar. She then hopped on one foot again to hit the other one closer to the second bar. Once she landed, she braced herself on the bar and did a high kick to her right to hit the mark on the wall there. She then hopped under the bar and used her left leg to land on the spot where one purple mark was located. She then braced herself for another high kick to the left wall to hit the mark there. Once finished, Sunmi stepped on one more mark before landing on the other side without getting pelted by any water balloons. The door opened and she stepped inside. Kwangsoo and Yeonseok ran towards it but it closed before they got to the other side.

“Sunmi are you okay?” Kwangsoo called out for her.

“I’m fine, oppa. I was right. The purple course is for one person and the blue and yellow ones are for 2 people. Oppas, you guys have to do it together.” Sunmi said. She didn’t know that on the other side of the door, the men had their mouths open, gaping at the thought of trying to accomplish what she did.

“Are you sure you’re human?” Kwangsoo asked her while Yeonseok laughed. Sunmi laughed as well.

The two of them started trying but Sunmi could tell that they didn’t plan out the paths well because of all the screaming. She could only sit in the cramped space and wait for them to finish the course. After a few more minutes, Sunmi could hear Kwangsoo and Yeonseok on the other side of the door.

“We did it! Open up please!” The doors started opening and Suni crawled away from it to make room for the other 2.

“Yes! It opened!” Sunmi cheered with them. Soon she could see Yeonseok entering.

“Be careful, oppas. The ceiling is low.” She warned and watched as Yeonseok crawled a few steps in before Kwangsoo came in. Once his head came through the curtain, a lantern fell on his head. It rolled near where Yeonseok was.

“Forty-two?” Yeonseok read the number on the lantern.

“What the heck? What the heck is this?” Kwangsoo complained of pain.

“Forty-two.” Sunmi tried to think about what the number could mean.

“Who the hell builds a house like this?” Kwangsoo was getting more irritated by the minute.

“What about forty-two?” Kwangsoo asked when he calmed down a
