Yoona's POV

"Hyoyeon unnie, come here." I whispered. She came and sat beside me "What do you want?" I smiled and whispered "I feel like doing a prank. It's been a while since I did one."

I explained softly "We'll put plastic layer first so that their shampoo won't mess up with the colour shampoo. Then we'll put the colour shampoo." Hyoyeon unnie nodded "Let's do it tonight."

Those hair colours suit each of you." Chanyeol stood up "Really?" Each of the girls nodded and gave thumbs up. Yuri looked at Yoona and Hyoyeon. These girls... Must have been them.
