-Nayeon's POV-

"I am really sorry Jungkook but can you just wait 5 more minutes...I am helping V over here..."

Krystal raised her hand and asked for help.

"Sorry Krystal, can you please mark yourself."  I handed her the answer book.

Suddenly the answer book had been snapped away from my hand.

"What.."

"Hello, Krystal."  I saw Jeongyeon kneeled down beside Krystal and started to mark her exercise.

"Jeong-"

"Krystal, you did a great job today...let's go through your mistakes okay?"

I turned back to V.

"Ok...uh V, for this question..."

"Jungkook, remember to do your times and divide before you add or subtract numbers..."

"Yes, Jeongyeon."

"See you next week then."

Jeongyeon waved at Jungkook as he left the classroom.

"Hey, thanks for that."

Jeongyeon just ofter a hand with her palm faced up.  I quickly realised what she was trying to do, I slapped her hands.

"Ahh!  I need my payment..."

"I will count that as volunteering work."

"Give me at least a cup of ice cream, Chaeyoung needs to go home by herself because of you."

"I will give Chaeyoung ice cream in person, don't need your help..."

"Well, are you leaving now?  There are no students in the centre..."

"Not yet, still have other exercises to mark."

Jeongyeon sighed.
