“I hate you!!” Kai shouted, as he put down his books.

“Thank you~” you blankly said.

“You can’t even explain what Alpha radioactivity is!” he hissed. You just looked at him while blinking. “You !!”

“Yah! Kim JongIn!” Kris voiced.

“What?” Kai looked at the elder with still flaming eyes due to your reaction. Then he realised, “Hyung! This girl of yours can’t....”

“I’m not his!” you mentioned, glaring at Kai.

Kai rolled his eyes, “Fine!” he sighed, turning back at Kris. “Could you please tell her, that she needs to at least say something in this presentation or else there will be no graduation for us this year!”

Because of its very large mass with is more than 7000 times the mass of the beta particle, and its charge, it has a very short range.

You smirked, “Lunch?” you saw him nodded. You sighed, “We’re not friends. I’m just here just because of that .” With that you step towards the exit. “Keep that in mind, guys!” you warned before you left.

I was headed to my apartment went a hand grab my wrist. But to my reflection, I grabbed back that person’s arm and twisted it. After looking at his figure, I released his arm. “What are you doing here?”

Kris rubbed his twisted arm, bef
