Heart Trainer (TaeKook)

Chapter 1 : Chaotic

"Yeontan!!!! You come back here you brat!!!" Taehyung called out to his dog as he ran after him around the living room.

Taehyung's brother, Namjoon, came out of the kitchen after hearing all the commotion. As he appeared, Taehyung shouted at him.

"Hyung!!! Get him!!!"

And with that, Namjoon anticipated the hyperactive little pomeranian that was running towards him with a key chain in his mouth.

"Gotcha!" Namjoon said.

Taehyung stomped towards his hyung, shaking his head and pointing his finger at the dog.

"Tannie! I told you that my keys aren't chew toys!" Taehyung loudly said while getting his car keys from Yeontan.

"In the first place, Taeh, where did you even leave your keys?" Namjoon asked as he ruffled Yeontan's fur.

"On my bed! I just had to quickly go to the bathroom so I left it there." Taehyung said.

"You already know that he could easily climb up on your bed so you shouldn't have left it there." Namjoon said.

"So, now it's my fault? That's why Tan doesn't listen to me. You're always siding with him, hyung." Taehyung exasperatedly said.

"As Cesar Millan said, it's the owners that need to be trained, Taehyung." Namjoon said. "Look at Moni, he's just lying down on one corner, because I commanded him to do that."

"Ugh! Whatever. I'm late for work again!" Taehyung said as he grabbed his bag.

Before leaving he looked at Yeontan who was now sitting on the floor looking at him with his tongue out and smiling as if mocking him.

"Oh, you find this amusing? I'm not done with you yet. Just you wait when I get home." Taehyung said before stomping out of the room.

Namjoon chuckled at his adorable brother's actions and then looked at Yeontan.

"Hey, Tan? You want to ride on the basket of my bike?" Namjoon asked Yeontan and he barked, wagging his tail as if he understood him.

Namjoon just laughed and picked up the dog.

"Why are you like that with Taehyung, huh? You naughty dog." Namjoon said as he walked back to the kitchen where his husband was at.

"Jinnie, I'll just go for a quick ride with Tannie." Namjoon said.

"Okay. Hey, can you pass by the cafe and give this to Jimin?" Jin said, handing his husband a brown envelope.

"Oh, what's this?" Namjoon asked as he placed it inside his body bag.

"That's for our rent so you'd better not lose that, Namjoon! I'm telling you, if you lose that, I will get money from your art collection fund." Jin said.

"Yes, dear. Look, it's already inside my bag." Namjoon said.

"And you say that as if you haven't lost an entire bag before." Jin said, giving Namjoon a knowing look.

"Okay okay. I won't lose it, promise." Namjoon said before kissing Jin's forehead and heading out.

Taehyung arrived at his workplace, five minutes late from his scheduled time in.  He groaned and quickly ran up the stairs to the third floor. He knew that it would take time if he waits for the elevator, so he decided to take the stairs and make a run for it.

As he was rushing, he didn't notice that someone was also rushing down the stairwell.  As he turned the corner, he collided with the person so he ended up falling down on the floor, butt first. He accidentally dropped his bag, so all its contents fell out.
