I'm Not Gonna Fail This Time [Taekook]

Jungkook got startled at what Taehyung said, getting mad that he suddenly punched the older. Hard. The older groans, falling on the ground. He let out a gasp, crouching down beside the older.
"Hyung! I'm so sorry! I didn't mean to! I got angry and I didn't know what happened! It-" Jungkook is cut off as the older's finger is now on his lips. He stared at Taehyung, who laughs, shaking his head.
"That was a good punch, Koo, not gonna lie" Taehyung says.

"I didn't hurt you, right?" Jungkook asks, closing his eyes as he whimpered.
"Hurt me?" Taehyung asks, letting out a cry.
"Yes! You hurt me here!" Taehyung says, pointing at the corner of his lips. The younger opened his eyes.
"Give it a kiss" Taehyung says, giggling. The younger slowly leaned, the older was shocked but stood still. Jungkook's loses balance, falling on the older's chest. They both stared at each other, the older laughing before giving the corner of Jungkook's lips a kiss. He helped Jungkook up, ruffling his hair.

Jungkook blushes, looking down. Taehyung chuckles and held the punching bag.
"Let's start from the start" Taehyung says and Jungkook nods, giving a small smile.

"Okay, hold this" Taehyung says. Jungkook grabbed what the older handed, his eyes widening as he realizes what it was.
"H-hyung!" He yelled, hand shakily holding the gun.
"Kookie, this could be useful" Taehyung says before helping him how to properly hold the gun. The older then explains what he should do.
"So, I'll just shoot that thingy?" Jungkook asks and the older nods. Jungkook nods before pulling the trigger. It didn't hit the target. How disappointing(JK: Hey! Don't you love me?! A/N: Of course I do, you mf). Taehyung chuckles, standing behind the younger and held his hand, explaining everything. Jungkook smiles, nodding to everything the older said.
