Yes Shuhua

Shuhua and you (Minnie) have always been separate sisters, you auditioned as a competition in Cube Entertainment and were in the same group, competitive and rivals of each other. Miyeon and Shuhua came after having an ice cream at the nearby ice cream shop
You look at Shuhua with a disgusted face and then you smile at Miyeon, you say
"Hello Miyu (Miyeon) and Shuhua."
Shuhua looks at you with displeasure and reluctantly says
"Hello Minnie."

...yeah.
