So, as of now, I still haven't thought of a story plot but I will write this one. Oh, and I changed the description of this oneshot. 

"Nayeon Eonnniiiii!!!!" 

Tzuyu jumped up and down while shouting her eonni's name. 

"Eonni! I passed our exam todaaaayyyy!!!" She exclaimed excitedly. 

"Really Chewy? Wow! Congratulations!" Nayeon said then sang 'Congratulations' by Day6. 

"Eonni! Eonni! I did well in class tooooo!!!!" Chaeyoung said. 

"Excuse me, who are you?" Nayeon said to Chaeng. Chaeyoung pouted. "Just kidding, Chaeng. Wow you guys did well today. Now go and wash up, you gotta sleep already today."

"Eonni." 

Dahyun said with a cute tone. 

"Ne?" Nayeon said  

"Look at this, eonni" Dahyun said then jumped, startling Nayeon. Dahyun did the hand fart rap. 

"How was it, eonni?" 

Nayeon was just staring at her. "What is wrong with you?"
