Tilt your heads, readers. I'm gonna tease you real hard.

THWAACKK!!!


"Ugh!"

A loud grunt escaped Kai's lips and his head was snapped to the side upon receiving a powerful punch on his cheek. The punch was coming from none other than his own big sister, Myoui Mina, also known as the Black Swan Captain and the CEO of Myoui Fishing and Treasure Hunting Corporation.

The 15-years-old boy staggered back a bit before regaining his composure. Hissing in pain, he then lifted his hand and rubbed the sore spot on his cheek.

"That hurts!" Kai complained.

"Of course, I did mean it to hurt you!" Mina retorted.

"And you didn't hold back at all." Kai stared at Mina, pouting.

"No, I didn't." The older girl smirked.

"Is this a punishment?" asked Kai, switching their language from Korean into Japanese.

"You're mad because I sneaked out and went with my friends last night!" Kai said while lifting his wooden sword, ready to attack.

"Of course I'm mad! You said you were going to stay in your room and did your homework! But you sneaked with your friends and only came home in the morning! Where have you been last night!? You little brat!" Mina responded in Japanese as well.

"Well, I can explain! I have my reason!" Kai shouted as she jumped at Mina, his wooden sword was raised high above him. He then swung his sword, targeting Mina's head.

The Black Swan Captain shifted swiftly to the side, causing Kai to hit the air instead.

"You're always making an excuse! I don't want to hear your explanation anymore! You lied to me, Kai!"

Mina shouted as she kicked Kai from behind, causing the latter to fall face-first to the ground.

"Grrrrr!!" The teenage boy growled angrily as he began to feel agitated.

Gripping onto his wooden sword, he pushed himself up from the ground and faced his opponent again.

At this point, everyone on the backyard who was busy doing their stuff, now had stopped their activity and decided to gather and watch Kai and Mina's fight instead.

"I think I have seen this scene somewhere before." Nayeon frowned as she watched the scene with full interest.

"Yeah, I think so too. Where have I seen this before? Seems like a déjà vu." Dahyun commented.

"We've seen this many times on the ship. Seems like yesterday, huh?" Chaeyoung remarked.

"Tck. I still don't understand what they're talking about." Tzuyu said.

While Momo and Sana just stared and smiled at the scene.

Everyone was now drowning in nostalgia upon seeing the scene.

"I'm not a kid anymore, Noona! I can go out whenever I can and do whatever I want!" Kai shouted as he launched again.

"Tck! You stupid kid! You can't do anything without my permission! I'm your older sister!" Mina shouted back as she parried.

"Stop sneaking out at night! Stop going out without my permission! Stop partying with your friends every night! I'm your older sister! You should've asked my permission first before you do something or go somewhere!"

"But you said, I've grown up and I can make my own decisions!"

"Yes, but you can't do it without thinking about the consequences, Kai! You're still in school! You have to study! You stupid kid!"

Kai paused and smirked. "Tck! Noona, you know I rank in Top 3 in school. I'm smart and I don't need that much time to study. Call me stupid, but I'm still smarter than you, Noona! Everybody knows that!"

Everyone who was watching them didn't understand what Mina and Kai were arguing about. Only three people understood it, that is Momo and Sana, and Chaeyoung. Chaeyoung had managed to catch most of the words, since she was a geek and has been learning a lot of languages ever since she joined Mina's ship five years ago.

"What did you say? Take this!" Mina swung her wooden sword very fast, and with so much force, that everyone thought she was really going to kill her little brother.

Kai parried with all his might. But Mina's force was a bit too much, it made him losing his grip on his sword. His sword fell to the ground, and Mina kicked it away.

Everyone thought their fight was over, but it was not.

After disarming Kai, Mina threw her own sword as well, leaving both of them empty-handed.

"1-0 for Black Swan Captain. Now round two! Get ready, Kai!"

Mina raised her both fists like a boxer.

Kai raised his fists as well, and they started circling each other.

Everyone continued watching.

"Are they really just practicing? This isn't look like an exercise at all." One of their workers, an old woman who worked for them as a maid, said with a worried look on her face.

"Yeah, don't worry, they're just practicing. We used to do this since we were children." Momo said shrugging.

"Take this! And this! And this!" Mina said while punching Kai on his left cheek and right cheek, over and over.

"Ow! Ow! Oucchh!" Kai groaned in pain, trying hard to defend himself. But Mina was much stronger than him. And Mina's punches were really not a joke. She's probably able to d
