G-Friend's Yuju transformed into a cute fan girl during the group's Christmas party via the 'V' app on December 21. 

The girls were explaining why they chose specific keywords for each month which were stuck to the strings of their balloons.  Eunha said while they were doing this, "Yuju has now become a senior to Sowon. That's why she even bought [Sowon] something yummy," revealing news of Yuju's entrance into college! Sowon has not yet entered college, so once she does, she'd technically be a junior to Yuju in academia despite being older.

Yuju then revealed the keyword for October was Kim Yuna, the figure skater. She revealed herself to be a huge fan of the athlete since she was a young girl, enough to have created a scrapbook, which she revealed on air! She said, "I made a scrapbook with scraps from newspapers about her gala shows and figure grand prix finals. I even stuck here the face of Kim Yuna which I had stuck to my lunchbox. I met Kim Yuna, whom I could not express through words how much I like her, at the [beauty shop] in October," unable to hide her happiness. How cute!
