The members got asked to name a moment when one of the others members was shining the most
Sana: For the moment when Dahyun-chan was sparkling the most...Dahyun-chan is really good at playing the piano, so seeing her play the piano on stage, and getting to show all her fans her charming performance and calm appearance was definitely the time she was sparkling the most in my opinion. (DH: Thank you!)
Dahyun: Honestly, Tzuyu-chan is always...(SN: sparkling!) yes, she's always sparkling. Even when she's eating a meal! But the time she shines the most is when she's on stage.
Tzuyu: (About Sana) When she's on stage, she shows off her sexy appeal that charms people, and because she has that appeal, the time she shows it is when she sparkles the most.
(Note: good job to Dubu for speaking in Japanese!)
Momo: For Jihyo-chan, on our tour this time, when we sang "Feel Special," and she stepped out in the middle to do her acapella, I think that was the time when she was sparkling the most.
Jeongyeon: I think that when Momo was dancing, it was like that of a powerful boy group, so that was when she was sparkling the most. (Momo: Thank you!)
Jihyo: Jeongyeon has dyed her hair so many times that it's started to hurt, and she's sometimes had to use an oily coating treatment for it. So at that time, she's quite literally glistening! (JY: No, it's not like that! JH: But you were!~)
Nayeon: The moment when Mina was sparkling the most...Recently, for her solo stage, I had the chance to watch from in the back, and it was just so cool; I was so glad I could watch her sparkling like that. Personally, I like Mina's basic, unstructured form, so it's because of that I think she was shining the most.
Mina: About Chaeyoung-chan...(NY: She can't be happy if she can't understand your comments in Japanese!) Whenever there's pen and paper available, she always starts drawing pictures. I think it's so cute how she silently draws the things she likes, and she seems to be having fun. I think you're always sparkling the most when you can freely do the things you enjoy.
(NY: Wow, that was a totally unexpected answer. CY: I think so too!)
Chaeyoung: When Nayeon is on stage performing with her bright smile, that's when she shines and glistens the most. It's so cool when she smiles and sings in her high voice with ease.
